May be a candidate for color holography or DCG.
Depicted as single frequency - 15mW, but seller only guarantees that a laser beam is emitted.

In the specs they specify 2 TEC's and so on. But no ring design.

No ring no joy...

Not necessarily.
Although no ring, C315Ms are perfect for holography, super stable with a coherence length of many meters.

Stability might be an issue though.
Dave, please report your results on the forum.

These lasers are problematic and the sellers are known rip offs. I myseld bought one some months ago and sent it to Sam. He was able to get it working under 10 mW, not reliable and never tested it for SLM as it was too flaky to keep. These are 5 mW spec lasers or most of them are. Save your money for something good. If you do buy one...good luck! Phil 142laser

These were tested by the company I worked for last year. Most of the ones we tested did not work, and I don't recall any making rated power or not having some issue.

I should say, we tested everyone for them as part of a contract we had with them. So everyone of these units has been tested and was marked with functionality on the power supply and head, the fact that they don't have labels means that they took them off because of the poor performance figures.

Does the Novalux 488nm laser really need a VGA connector between the power supply and head which carries 4 amps and is rated at 80V? If so, where would you find such a cable?
Thanks
