Any affordable UV diodes/DPSS systems?

Are there any affordable UV diodes/DPSS systems out there? I'm not talking about 405nm.. I'm looking for <400nm.

Power is more or less irrelevant.. 1mW would probably be sufficient.

Mmm we're looking to incorporate some kind of UV laser into our cancer screening device. The UV range <400nm provides the most useful information, but since we're trying to keep the cost low so that it's affordable for underdeveloped countries, it doesn't look like UV will be doable :(

The laser diodes are coupled to 100-200um optical fibers which are pressed against the skin of a patient. another fiber adjacent to that probe fiber is then connected to a photodiode to measure the reflectance/scattering.

We are also looking into LED's but LED's being a noncoherent light source, it's hard to get a usable amount of light into the fiber and back to the photodiode.

If there are no UV laser diodes available you'd end up with a tripled yag laser, not the cheapest. You could look into nitrogen lasers, but those have a horrible beam quality and probably won't get much light in the fiber.

CNI sells some 365nm or so modules, you will have to contact them for pricing though ;)

They manufacture most DPSS modules out today.
