I need to mix two red 638nm beams together I already have a PBS cube so I'm looking for a Red Polarisation rotator/waveplate, could anyone here direct me to a good supplier ?
thank you for your reply, I spoke to the guy that runs DTR and was informed that I can not modulate the sharp 700mw diode, I'm not really bothered about the divergence of the USHIO for now as I just want to get something up and running :)
Hi guys , I use to work with huge water cooled gas lasers many years ago (about 20 years) but have been out of the game for some time. now that there are so many laser diodes about I've been tempted to get back into the game at a hobby level so I'm putting together a small laser show projector...
