High Repetition Rate 1535nm Microchip Laser Module
High Repetition Rate 1535nm Microchip Laser Module

Er:glass Eye-safe Lasers are diode pumped, water-free, passively Q-switched lasers independently developed by Reallight, combine eye-safe wavelength operation with high peak power, short pulse duration(pulse width), and diffraction limited beam quality to deliver unmatched size, weight and power.

Our Eye-safe DPSS Lasers operate at 1535nm, In addition to being called 1535nm lasers, these lasers are also called 1540nm lasers, 1534nm lasers, 1.54um lasers or 1.54μm lasers, widely used as the emission light source of rangefinder . At this wavelength, eye-safe laser ranging systems can be easily configured without compromise to beam power or quality. This makes laser ranging applications safer for customers. Most of these lasers are operational over a wide temperature range from -40℃ to 60℃, with lifetime exceeding 60 million shots.
