Lasever offers good laser here

[dsli_jon]

And we will give you cheaper price even than you can get @ ebay.

I have a new idea.. I'm going to suggest to Spec that any Co, here, that either constantly-sells stuff, and/or like 'David', here, who is just flat-out

... and is not - at the *very-least* a Blued site-supporting member, that they are automatically *forced* to have this very-image, put in their Sig-Line.. ya know, kind of like a 'scarlet letter', only funnier..

..You wanna Spam this forum? - OK, fine, but you're getting 'Spamstamped' ™ until you contribute something meaningful / helpful to all, at the *very-least* being a site-sponsor (contributor..) Everyone here plenty-well knows how to use Google / eBay, when they wanna find a 'cheap lazer'..

Dos centavos..

..the internal design is bad for such a powerful laser (no separate TEC for the crystals !!!), make me think I will never again buy a chinese laser, even if I have to put several times the price for an equivalent power, as I already do with red and blue lasers. It's way too risky if your own laser business is growing to a point...

My sentiments, exactly... you 'pay now, or you pay, later'... choose one.. And, sure - not as much 'risk' for the 'hobbiest', but.. I feel safe in venturing to say that, ie: 'Mr Yayas' would probably-prefer to have the 473 he payed X-$$ for, actually working, instead of him having paid X-$$ for a paperweight, ya? Most people already-have plenty of 'rocks' in their garden for such a purpose..

..anyhoo, I rant into the wind, yet again..

I have no bad experience with lasever at all. I just wouldnt buy another module then their 532nm's because their beam size and mrad is not really great.
David from lasever always helped me with all questions. Also had to return one another day. NO problem.

What i dont like is their prices. 900 dollar for 2 modules put together with pbs with a total of 1.2W.

Hi Boaz,
I also donot like the price $900 for 2 modules coupled. They are 2x600mW lasers, one 1/2 waveplate. one PBS, two mounts, and baseplate and couple adjusting.

And a 1.2W single laser is for $650 only:-)

Hi Michael,

Sorry that you didn't experience best of Lasever and me! But some of your words are unfair for Lasever and me.

For the lasers you returned, I and my colleague wanted to select TEM00 mode lasers for you in months. I was sad that no higher than 700mW green lasers were TEM00. They are near TEM00. Thanks for your kindness! I selected lasers with small beam size and divergence that you accepted.

Well, I couldn't say that... I've just buy their new 2W head, with 7W pump diode into the 532-H (cni "MGL-H") head...

The max head output is 1.95W CW when it is with 5V in the modulation...

The output is 2W to 2.2W depending on each laser heads. There may be difference in different power meters. Our meters are caliboned periodly. We wouldn't offer lower than rated power.


[QUOTE=After 8 minuts in CW, the head is 38°C (16°C more than ambiant temp), and driver heatsink is 67°C !!!!!

Conclusion : The driver and head are totally inadapted for the pump diode.

The cost for this head is 400USD more than the 1.5W one (who output 1.6-1.7W). A total rip off when you pay 400USD more for 250mW...

What's more...![/QUOTE]

It is true that 2W in the LSR532H head is hotter than 1W and 1.5W. air flow or heatsink is suggested. The driver is better to be sided up. There are holes for mounting.

In fact, the power effection is very high in this 2W laser. Considering so small a size, the temperature on the laser housing is low.


The reason of the price is that 2W is difficult to make. 1 carat diamond costs more than two times of 0.5 carat diamond. Do you think they rip you?

[Lasever]

Oh, yes! I forgot the best thing...

I paid additionnal cost than the normal price for having a "selected" head with beam <2.5mm diameter. Why? because I planed to add a 2:1 telescopic for having a <5mm beam and divergence of 0,8mrad. On the datasheet, this is written that the head has 2.1mm beam diameter, so with telescopic this should be 4.2mm... I can take a picture of the "certification sheet" if someone want!

Only ten dollars for the telescope. It is really low cost. I didn't charge for selected head.

FYI, I refund $20 to your paypal because you canceled 2 of the telescopes.

[Lasever]

and about sending cost.... I paid 95 USD, not 40. Ok I had 2X 532-NL heads with, but I don't believe that the package weight was 2.5X heavier... and I live in a European country, not in a remote area.

Asked for a discount as I bought 3 heads (and I bought other heads before, so I am a quite good customer), at least only free shipping. I received NOTHING !!!!

2x LSR532NL laser unit and 1x LSR532H unit weigh 7 kg. The shipping cost is $40~45 for one LSR532NL 2kg. The shipping is 95$ for 7kg.
The quantity is not so big. We offer discount depending on quantity.

I think this is not Lasever the problem, but David. He believes that he can fuck the client like he wants, because we are living far from him. I've just seen a TV report who talk about these new "rich" Cheneeses who can affort Bentley, French wine bottle who cost thousands dollars. They take benefit of our higher lifestyle and money income. I said that, but the ones who know me, I am still student (!!!), so this is still really expansive for me.

it is not my conditions. We are hard-working technicians and sales men.

[Lasever]

About the data report sheet Michael mentioned, I am quite sure that we measure and put true figures. All of our clients who have the data sheet can see and check the truth.

Michael, I would send you a replacement if the beam is splitted into 2 beams. You may send me a picture of the beam spot on wall.

In a conclusion, Lasever and me are always with customers. We accept your criticals and improve to meet customers' requirements.

Happy weekend, friends!

David, what about the blue warranty module your provided me with that died with only 10 hrs or so of use. Well, not dead but only putting out less than 1/3 of what it put out when I received it.

/sorry to hear that. Please send it back for repair.

Guys-

Look, by NO MEANS am i putting ANYONE down. And i am in NO WAY "siding" with *ANY* Chinese company and/or particular manufacturer. But lets all take a step back and ask ourselves something...

Why are Coherent, Jen las, Laser Quantum, RGB Lasers, KVANT and MANY other *NON CHINESE* Laser products so much more expensive? I'll give you a hint...IT begins with a "Q" and ends with "Uality." You all, as I am quite sure, are aware that I sell Lasers. I have dealt with almost EVERY single Chinese Laser manufacturer and I still carry one of them. and the BEST acceptible initial quality percentage I ever had from ANY Chinese manufacturer was about 60%. My average failure rate for Chinese Lasers (i just looked through all of my sales and returns, replacement and defect records is 62% (6 out of 10 Lasers had some sort of SERIOUS issue with them within 1 year) I judged this based on:

1) Worked properly, as described out of the box (Power, CW and Modulation)
2) No returns or defects within 1 year (All chinese modules have 1 year min. warranties as far as i am aware)

As a U.S. based Laser manufacturer, these records must be kept, so it is/was pretty easy for me to figure this stuff out.

My KVANT defective, repair, replacement and/or below spec percentage is about 1% over 3 years!!!!! the following numbers **are not** exact, but i am briefly and loosely looking at some numbers now-

Out of approx 120 KVANT Lasers sold, I have had 2 (yes, 2) sent back to me. Actually 1 was one of my own lasers for one of my projectors (of course. lol) and the other was a high powered blue that actually wasnt even a "KVANT" defect. More of just an overlook for a new product.

When you pay $1500 for a 2W Laser, OBVIOUSLY something (or somethings) somewhere is being "corner cut" to be make the product so much more affordable. Which is fine if you accept the lack of standards and performance quality. Come on guys...Accept much of this responsibility yourselves. you are buying EXTREMELY "hign tech" products from people and a nation who are taught, trained and expected to work for next to nothing, as fast as they can and in the CHEAPEST way possible. This is why a 2W "Chinese Laser" is $1500 and an American Coherent Laser is $8000. You get what you pay for. It is VERY simple.

I am in NO WAY condoning poor product quality or data spec exageration. But You can not pay Honda Civic prices and expect to get a Lexus performance. "Above Average" Chinese performing Lasers are NOT THE NORM. They are an exception.

Many of you (honestly, myself incuded in many circumstances) have gotten EXTREMELY spoiled with cheap Chinese pricing. I hear it everyday on the phone regarding shows and sales of equipment. Lasers are supposed to be expensive. They are LASERS not flashlights from Wal Mart.

If you REALLY need to spend less than what quality costs, than i would suggest buying 2 of what it is you are buying. Because chances are and statistics prove- Your cheap Chinese will fail you and not perform as expected much quicker than you assume.

Now, all that being said- 3 of the very first Laser modules I ever bought (solid state) were actually Lasever in ~2005. 2 are still working perfect (635 and a 473) Power is exact same since day 1 and the third just died about 3 months ago. So, i have had a GREAT experience with Lasever. This further proves the point of inconsistency of Chinese products.

If you need quality and perfection (or close to it) Than you need to *INVEST* in it and not expect sub-par products and below standards, engineering/manufacturing practices to perform as properly engineerd and manufactured PROFESSIONAL products!!
