New 900mW 642 (640)nm KVANT module born!

[pelosh]

Hi everyone!

It has just been tested and it is quite good.

3x3 mm beam with 1.4 - 1.5 mRad divergance at full angle.

Price: Just under 1500 euros.

Divergence is way to high...

wow that sounds like a bitchen laser! Do you have any more info, or pictures? Not like I could afford it, but that's allot of red power! The divergence isn't that bad, considering the power plus it's not DPSS right?

Hello!
How big is the head and the driver? Is it tec stabilized? Do you have pictures?
Greetings,

hi martin do they make a 300mw one? and how much are they?

[tocket]

That's a nice laser! Quite pricey, but half the cost of a 1W SwissLas 642nm, so I guess it's a good price.

What's the polarization?

Pics!

Do I get a discount if I buy this together with a 450nm blue?

Hi guys!

I have to apologise for BIG mistake on my side due to misunderstanding between me and supplier and the price is 1815 euros right now....sorry about this, but mistakes can happen.

OK, now bit of tech. info:

It is Doide laser, TEC stabilized, Analog 50kHz, signal horizontal polarization.

Picture will come soon!

Hey Chris...300mW version is 690 euros + VAT unless you are registered (IT REALLY IS WITH NO MISTAKES).

Despatched within 5 working days after order confirmation and pre-payment recived.

Now you can shoot me...I am waiting

How many diodes in the module ??

Is it being "overdriven" to achieve its rated power out or is it "cruising".

I have been looking into these 640-645 units and there seems to be a variety of configurations...
Most claim about 1.0 mrad divergance.

Some claiming relatively high powers on low diode 'count'..

The more expensive units seem to be using six diodes... like Arctos and Swisslas ... guess you pay for quality.

Hopefully this new unit is also in the "cruising" category.

Unless there's some brand new, totally different, really really secret 640nm diodes about I would hazard a guess and say this module uses 6x 150mW diodes running at more or less max current and looking at the beam spec of 3x3mm and fairly high divergence is probably using very high NA short FL collimators (something like the LENS27 from Roithner) to "simply" combine them.
Of course this could all just be twaddlespeak

I have seen these diodes produce over 165mW at max spec current and (again guess) that the manu's are pushing 150mW/diode so 2x for a 300mW, 3 for a 450mW etc, but again this is guesstimationalising.

As they don't spec a pulsed driven figure (like DVD diodes) I wouldn't like to say how they will last if pushed hard and I can't see anyone selling a module with 2 diodes spitting out 450mW.

It'll be interesting to see what unfolds over time as owners get the lids off these modules and post pics...

I can answer straight away for KVANT modules.
They are using 6 diodes, each doing its original nominal load of 150mW.
No stressing components at all.
