The new FRLD-1535-xxxµJ-Q-BEyy series of laser modules are an integrated 1535nm high-energy erbium glass microchip laser with up to 40x beam expander and photodetector (PIN). This series is specified to deliver high peak power of 5μJ-1J at 1535nm with divergence angle of less than 0.3mrad, and provide PD output signal. The operating temperature range is very wide and covers a range from -40°C to +65°C. With dimensions of just 78~83mm x 32mm x 20mm they are very compact. Their high repetition rate, small pulse Width (FWHM), high reliability and compact structure makes them perfectly suitable for various target designation applications: laser ranging, laser remote sensing and lidar.
