DFB Single-frequency laser diode

The high-power single-frequancy butterfly-packaged DFB laser adopts a hermetic 14-pin butterfly package. The module integrates additional functionalities including a thermoelectric cooler (TEC), thermistor, and photodiode (PD). Rigorous performance and reliability testing ensure exceptionally high stability and reliability of the laser. Characterized by narrow linewidth and high power output, this laser is primarily used as a light source for pulsed narrow-linewidth fiber laser systems and direct frequency conversion applications.
