Do you mean this picture ?

Yeah good question , i didn't really noticed. i Just took pictures like hell before Martin's collegue closed it up again hahaha.... Maybe Pelosh can explain what it is ?
Some beam shaping optics maybe ? I dunno, since i don't have coherent money ;-)

It's a red OPSL module...

So it is!
Must be to bring the beam size down at a guess...

**Francesco** · 03-31-2010, 13:12

The red OPSL actually has a blue OPSL as pumpdiode

Now take a guess what that magic extra part on it is...

**danielbriggs** · 03-31-2010, 13:13

Whoaa!
Well I never...

**andy_con** · 03-31-2010, 13:15

Then isnt it possible to multiplex the blue beam into a blue and a red beam?

If you put a 60K galvo in front of the red chamber to direct the blue beam onto the blue dichroic, and to the red chamber you could have a red and a blue at 30Khz pulsed each.

No idea if that would be possible, but there is actually a small leackage of blue in the red OPSL.
