LD-PD's narrow-linewidth 509 nm single-frequency laser module features selectable output wavelengths from 507 nm to 512 nm and a linewidth of less than KHz. This series adopts a modular and compact optical design, offering miniaturization and high output stability. It operates on a 12 V power supply and supports RS232 serial communication, allowing users to set and monitor the module operating status via host computer software. The module integrates a built-in PZT and amplifier circuit, and provides a PZT RF signal input for convenient PZT scanning.
