Opt Lasers 900 mW 638 nm Free Space Laser Diode Module features excelent divergence and beam size specifications. Laser diode driver prowided with this module ensures precise controll of laser diode current, while maintaining high speed modulation. Precise controll of temperature of laser diode housing greately improves power stability and ensures long lifetime of the laser diode. This combination of beam specifications and current, temperature controll makes this module a perfect choice for both scientific and industrial aplications.
Because specifications for each module can be slightly different Opt Lasers privides characteristic card with measured power, wavelenght, spectral width, peak-to-peak and RMS power stability over 8h, and beam profiles for each module.
Cooling platform and PSU for this module are available for this module. If you want to add them to your orther or have any other questions feel free to contact us.
