I'm going to see what my 470nm diode looks like once I get the spec calibrated. I might be able to temp control it to 473nm and use that. It's 30mw so that will be plenty. 10mw is really nothing for lumia and gets buried. For Raman the diode might be better. Need clean up filter of course. https://www.edmundoptics.com/optics/...ndpass-filter/
Speaking of which this diode is one of these. What mount fits these without decanning? https://sites.google.com/site/dtrlpf...nm-laser-diode
I'm thinking the ball lens will be a benefit loading the fiber in this case.
