NOTE:

1. Anti-static measures must be taken during transportation, storage and use.

2. Laser diode pins need to be protected by connecting short lines between them.

3. Use constant-current power supply to avoid peaks and surges when working.

4. Do not exceed the specified operating temperature, frequency, pulse width, current, etc.

5. The laser must be installed reliably (following the instruction manual) to ensure proper operation.

6. Ensure that the laser window is clean and pollutant-free, to avoid light abnormalities.

  

STXL Series Microchip Lasers

2.1 STXL High Repetition Rate 1535nm Microchip Laser Module

Er:glass eye-safe lasers are diode pumped, water-free, passively Q-switched lasers independently developed by us, 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.
