Looks great... any background? What is this? How much did it cost you?

Yeah , sorry forgot to add , this was a 750mw rated 671nm DPSS laser head , i got it a wile ago for around 200usd the driver was dead and tec driver were damaged i got a flexmod 2 to replace diode driver , and then i need to sort cooling out , this does burn tape when focused but not fully sure on output power .

Wow, 750 mW that's a very powerful laser! I guess now you can change your signature since you have this laser.

Well im kinda stuck the tec driver used didgital sesors but they dont work anymore so i need a way to attach new anoloug sensors - like a thermistor to each mount then use driver to regulate temp of the 3 mounts . But im not sure , would be nice to get over 500mw out of this laser .

funny how the IR of the laser makes it look like white light on a camera (you did have goggles on, did you? it sure doesn't look white to you).

I have goggles for IR , even with them off the light would be invisible to me apart from the 808nm wich would be very faint . my othere camera pics up the 671nm as a pinkish colour

I would recommend contacting robin at Die4LASER. He makes an active TEC driver called die4chill.. I believe that it uses thermistor input to regulate temperature. Just email him at the address at the top of that page.
