375nm Laser Diode, 50mW , Turn-Key Module

375nm Laser Diode Module Overview:

These laser diode modules include a power supply to safely power the laser. The center wavelength is 375nm and the output power is 0 to 50mW. The output power can be adjusted by the user. The source laser is thermally controlled and protected by being mounted into a cooled housing. In addition to protecting the source 375nm laser, the integrated thermoelectric peltier cooler stage and mounting plate delivers stable wavelength.


Key Technical Parameters:

These modules were designed to run for longer periods in continuous mode (CW) and deliver power stability of +/- 1.5 percent over four hours. An optional version with sub one percent is available on request. They offer transverse mode near TEM00 and an m-squared beam of less than 1.5. The beam diameter is one millimeter. The integrated control unit requires a laboratory grade 12 volt power supply.
