The DBR816PN from Thorlabs is a Distributed Bragg Reflector (DBR) Laser Diode that operates at 816 nm. It has an integrated optical isolator, thermoelectric cooler (TEC), thermistor, and a photodiode. The diode delivers a CW output power of up to 45 mW. It has a forward voltage of 1.95 V and a threshold current of up to 54 mA. The laser diode is available in a 14-pin butterfly package with PM780-HP polarization-maintaining optical fiber and an FC/APC connector. It is ideal for water vapor differential absorption lidar (DIAL) systems and can be used as a low-noise pump source for near-infrared spectroscopy (NIRS).
