I found this site while surfing:

They make UV, violet, and violet-blue laser diode modules. The purple anodized cases are a nice touch.
I tried to find prices, to no avail. I hate it when companies and their distributors don't post at least a price range.
Here's the specs to slobber over
Wavelength 405 nm (-5 ... +10 nm)
CW Power 50 mW
Beam Mode TEM00
Beam Diameter (at window, typ.) 3 mm
Beam Divergence < 0.6 mrad
Polarization [ch8805] 100:1, Linear
Power Requirements (max.) 10 W
Input Voltage 5 V
Length 150 mm [ch8709] 30 mm
External Control Interface Analog power control & TTL modulation
Weight 250 g
Environment
Operating Temperature 10 ... 40°C
Storage Temperature -20 ... +60°C
Wavelength 445 nm (-5 ... +5 nm)
CW Power 40 mW
Beam Mode TEM00
(other specs are the same)
