Beennnn... That's luke's job... ;)

Thanks Ben:)

I'd like to update a pic of this unit.

Yes, The promotion price now is including all the shipping cost to all over the world.

Thanks,

Luke

Hi Luke, I hope you received the email I sent you about laser testing!

I have the same design as on picture and so far it was good to me.

Thanks Alex,

If the laser doesnot work good for you, tell us here, we are easy to improve and work together with our clients.

If the temperature in your Canada is too low , you'd better warm up the laser before using, it will be usefull for its lifetime:)

All my best ,

Luke

Hi Luke,

may I ask who is the manufacturer of the laser?

On your website you have red lasers 200/300/500mW 635nm with divergence < 2mrad. Do you have a special price on those lasers as well?
I'm sure a few people here will be interested.

Hi Matthijs,

They are made by S-KY(www.skylaser.cn / www.laserbtb.com ).

Sorry, but we donot have promotion price on red lasers, and the 1W green will last till Jan,04,2008.

For 635 reds, we launched a new type to control smaller beams, <1.5mrad @ 2mm-3mm. Typically 500mw, 1000mw, 2000mw.

Thanks,

Luke

I don't mean to be rude, but those specs are not even physically possible unless you have an emitter with a stripe of about 180uM or so. At that point, there is NO way to get 1W or even 500mW. Sorry!

Hi ,Ben

Thanks for your comments.

Our engineer told me the elements is probably like this – it means fiber coupled in the laser head box, and then collimation at the aperture. Do you think it possible?:)

Luke

I understand what you mean, it's one of the very fundamental laws of physics and optics. You cannot increase the brightness od a source. This means, if you have a 1mm square emitting at 10mRad and you want it to be 1mRad, you have to make it 10 times the area for basic thought. While there are a very few exceptions to this rule. The most understandable being that you can technically "increase" the brightness using a lasing medium such as Nd: YAG, you cannot do so with a diode. (there is a way, but I will not discuss that.)

The reason for the fiber is the same as using an anamorphic prism, it compresses and circularizes the beam beking the output round instead of square/rectangular. An example of this can be seen here where the 19 emitter bar is coupled into 19 individual fibers then the fibers are put next to each other to make the output more round.

Thanks, I will update a pic here about the new type 635nm reds after it come out.

Hi alll
1.5W 635nm red lasers, with PCB in laserhead. wish all of you will like.
please remember this is Bridge,our corporation is Beijing Laserwave Optoelectronics Tech.Co.,LTD ,www.laser-wave.com.
more pictures you can see in my gallery: www.photonlexicon.com/gallery/bridge

Wow...Thats beautiful Bridge
Hows the beam profile?

Hi Forum,

We checked and tested our 1W,GREEN on promotion, There are still 2 units up to 1300MW, there are still 5 units up to 1200MW, The lowest one is 1090MW.

Welcome to order and test our quality.

Cheers from China,

Luke

Hi all,

Exactly, On the promotion 1W green lasers, we now have --
1unit ,1.26W @ 4% stability, 1.2mrad(full angle) @ 2.5mm (at aperture)
1unit ,1.24W @ 3.6% stability, 1.2mrad(full angle) @ 2.5mm(at aperture)
1unit ,1.23W @ 4% stability, 1.1mrad(full angle) @ 2.5mm(at aperture)

However, the lowest unit is 1090mw, the promotion will be ended before JAN,04,2008.

Greetings from China,

Luke WANG

Ok, The new year is coming also Jan,04 2008 is coming. We are going to end the promotion item.

Thanks to some our old clients test again our this green unit, thanks to some the new clients perfer to try our quality. I would like they post directly here if they have any enquiry to our quality.

Happy new year to everyone, Buyers, Suppliers, and hobbyist .

Greetings from China:)
Greetings from S-KY;)

Hi Luke,

I just got the laser today and I am very excited to test it! First challenge was the fact that the power plug was a china style one and I didn't have a proper adapter, other then that, it's very nice! I'll get to the final tests tomorrow!

Any update on your tests?

I'm talking with them about building me a custom portable < 500mW unit, and would like to know your experience.

Hi,

Because that's not free sample, I think people are not very active to post test result of not free:). There are some link from my email box --

Hi Luke!
Thank you, we received the laser today: our technics will check it at the beginnig of JAN and we shall contact you asap...!
With best regards and wishing you a prosperous NEW Year!!

hi, i revived the laser and it looks good to me. i will contact you in the
future for my lasers
