The DBR895PN from Thorlabs is a single-frequency laser diode that is well-suited for a low-noise pump source for Cesium atomic clocks, second harmonic generation, and time-resolved fluorescence spectroscopy. Operating at 895 nm, it provides an output power of over 10 mW. The laser includes an integrated optical isolator, thermoelectric cooler (TEC), thermistor, and monitor photodiode. It is packaged in a 14-pin butterfly package with PM780-HP polarization-maintaining optical fiber and an FC/APC connector with the connector key aligned to the slow axis of the fiber.
