1535 solid-state eye-safe laser—Ultra compact eye-safe laser 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 have already used in ranging finder and its ranging range is 3-5km with high stability, which applied in Gun aiming and UAV pod.
Lasers with emission wavelengths longer than 1.4 μm are often called “eye-safe”, because light in that wavelength range is strongly absorbed in the eye’s cornea and lens and therefore cannot reach the significantly more sensitive retina. Obviously, the quality “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 particularly important in 1535nm-laser-for-ranging-and-radar cases where light needs to be transmitted over substantial distances in open air. Examples are laser rangefinders and free-space optical communications.

——growing crystals, linking values

We are seller of crystals. At same time, we are producer of crystals.

It is a long and arduous process from seed crystal to the desired single crystal, the composition of the crystal changes through three states and eventually grows into beautiful crystals. We witness the growth process of each crystal and clearly know technologies of each step in the crystal growth process, which means that we can directly provide customers with crystals that satisfied customer requirements.

We create value. At same time, we link value.

From company to individual, we all pursue the word "value". Individual is valuable in society, enterprise is valuable in the industry. We cherish the existence of value. We hope to set the enterprise’ value as start pointing, expand to the surrounding, extend the value from the customer to the supplier. Linking enterprise and the industry more closer, to create more value.
