1535nm Er Glass Eye-Safe Solid-State Microchip Laser — Ultra-Compact DPSSL for Ranging Finder

The wavelength of 1535nm is just in the position of the human eye and the atmospheric window, so it has been widely concerned in the fields of laser ranging and electronic communication. Er,Yb:glass lasers are most commonly used for laser rangefinders with a low pulse repetition rate (less than 10 Hz). Our eye-safe laser has already been used in ranging finder, and its ranging range is 3-5km with high stability, which is applied in Gun aiming and UAV pod.

Lasers with emission wavelengths longer than 1.4 μm are often called “eye-safe” because the light in that wavelength range is strongly absorbed in the eye’s cornea and lens and, therefore, cannot reach the significantly more sensitive retina. The quality of “eye-safe” depends not only on the emission wavelength but also on the power level and the optical intensity which can reach the eye. Eye-safe lasers are essential in 1535nm laser for ranging and radar cases where light must be transmitted over substantial distances in the open air. Examples are laser rangefinders and free-space optical communications.
