HCSEL laser

HCSEL is the abbreviation of Horizontal Cavity Surface-Emitting Laser. HCSEL laser is a semiconductor light source. It’s developed based on compound semiconductor materials. Similar to the structure of an EEL (edge-emitting laser), the HCSEL horizontally laser cavity uses diffraction optics to form surface light perpendicular to the laser oscillation direction. Usually the operating wavelengths of […]
