1535nm Erbium Glass Laser Module  With Beam Expander
1535nm Erbium Glass Laser Module With Beam Expander

1535nm Erbium glass laser module with beam expander is an integrated laser module composed of erbium glass microchip laser, beam expander and photodetector (PIN) independently developed by RealLight, which is professionally used in laser ranging, laser remote sensing, lidar and other applications. The R1535-25X series of laser modules are specified to deliver 100-300μJ at 1535nm with divergence angle of 0.5mard, and provide PD output signal, which has the characteristics of small size, high reliability and wide temperature operation.
