Have any 365nm laser diodes become affordable?

[Franquixote]

A bit of a cross post in the "Non-Flashlight LED Forum "- I am beginning what I expect will be a long-term project to get the smallest, brightest 365nm light source possible for use with my strontium aluminate glow pigments. I spent a few years finding the ideal pigment (size, manufacturing practice, etc.) and now I need a way to miniaturize the light source. This is intended to be a replacement for tritium. If anyone else wants to join me, I am willing to talk to potential partners in this.
