Just bought a Laser-wave 640!
So, I just bought a 200mW laser-wave 640nm module
Anyone else got one? How do they (over)perform?
Also, I have been told they can be combined with another red laser with a PBS cube, which means they must use a single 640nm diode? How do they correct the beam size?
Now to play the waiting game, hopefully EMS doesn't take too long!
I'll probably do a review on it when I get it too.
Cheers,
Dan

Overperforming would be a bad thing on these I would guess. Since it's direct diode, it would mean it is being overdriven

That's not necessarily true. It's very possible that they use multiple diodes and re-polarize the light before collimation with a polarizer or wave-plate.. It would be easiest to just use a multimode diode that provides the proper amount of output and then shape the beam using custom optics or fiber.Originally Posted by Things
Enjoy your new laser!

*yes* they can be combined via a PBS.
You'll love it! very small also.

I have one. Same thing 200mW@640nm
It performs great!
The beam is extremely tight. Fits perfectly with green and blue DPSS lasers. You won't be disappointed.

Ant the usual question: price?

What diode is inside?

Have you got any pics/vids of it, and the dot/beam? I can only seem to find pix of the larger modelsI have one. Same thing 200mW@640nm

Should be here this week sometime, as long as EMS isn't bogged down for xmas too)
As for price, I'd get in contact with a distributer closer to your area

I've just picked up a 350mW 640nm unit, and roughly swapped it out out for my ~400mW 660nm,
and it makes a hell of a difference.
I mean a SERIOUS difference.
It now makes colours I never though possible...
Images and that to follow of the updated build soon-ish...

Hey Dan... You need to combine those babies, ask RobI've just picked up a 350mW 640nm unit, and roughly swapped it out out for my ~400mW 660nm,

I have a dual Maxyz 660nm and the 640nm Laserwave combined and the red is beautiful
Best of both worlds
