Note: Your Quotation Request will be directed to Thorlabs Inc.

The FPV785P from Thorlabs is a 785 nm Wavelength-Stabilized Laser Diode is based on quantum well epitaxial layer growth and a highly reliable ridge waveguide structure with external volume-holographic-grating (VHG) feedback. This laser diode produces a wavelength-stabilized spectrum with a single-frequency narrow linewidth over the operating power range of approximately 30 to 50 mW. This single-frequency laser diode is housed in a butterfly package with an internal optical isolator, monitor diode, TEC and a thermistor that allows the laser to be temperature controlled. The output is coupled to 1.0 m of FC/APC-terminated PM780-HP fiber.
