The DBR795PN from Thorlabs is a single frequency Laser Diode that delivers an output power of 40mW while operating at a wavelength of 795nm. This Distributed Bragg Reflector (DBR) includes an integrated optical isolator, thermoelectric cooler (TEC), thermistor, and monitor photodiode. It is available in a 14-pin butterfly package with a PM780-HP polarization-maintaining optical fiber and an FC/APC connector, which is aligned to the slow axis of the fiber. The laser diode is well-suited for low-noise pump applications such as 87Rb D1 transition; second harmonic generation; and time-resolved fluorescence spectroscopy.
