March, 2023: High Peak Power 1535nm Erbium Glass Laser Module with Beam Expander and Photodetector. 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.


Gun Sight Mini Lasers

FLC gun sight mini lasers are customized compact structure laser diode modules with various single mode wavelengths (450nm, 520nm, 635nm, 650nm, 780nm and 850nm), different output powers (≤0.4mW; ≤1.0mW; ≤5.0mW), small beam sizes (≤6x12mm@10m & ≤10x20mm@20m) and very compact housings (Φ3.3x8.0mm; Φ3.85x8.5mm; Φ4x8.5mm; Φ4x10mm; Φ6x12mm). The input voltage varies from 3V to 5V DC and the input current range is from 25mA to 120mA. The mini laser modules can be driven in continuous or pulsed mode. Their small size, low power consumption and compact structure makes them perfectly suitable for various target designation applications.
