Er:YAG performance

Er: YAG crystal has a rich power level structure and also excellent laser performance. It can stably release lasers with wavelengths of 1.64 μm, 1.78 μm, and 2.94 μm, permitting high-concentration ion doping, and also the power level lifetime of the laser reduces when high doping is used. Small, the laser efficiency is improved. The 2.94 μm emission wavelength of Er: YAG with a doping concentration of 50% is located at the water absorption optimal, which can be strongly soaked up by water particles and also can additionally be absorbed by biological tissues. Because the absorption coefficient of water at this wavelength is 100 times larger than that of 2 μm and 10,000 times larger than 1 μm, the 2.9 μm laser word has crucial applications in the medical area.

Applications of Er:YAG crystal

Er: YAG crystals have been used in medication, such as dental surgery, cosmetic surgery, as well as ophthalmology. As well as Er:YAG laser wavelengths can boost different skin conditions, such as actinic photodamage, hyperpigmentation, traumatic scarring, rough skin appearance, laxity, etc. Additionally, with the growth of laser modern technology, Er: YAG pump lasers additionally have applications in the army area and also melon optical communication, such as lidar, telemetry, as well as active imaging.

The manufacturer of Er:YAG crystal

In the context of the continuous expansion of the laser industry, the Er: YAG crystal market space is also boosting. Currently, international business generating crystals primarily consist of Fabrinet in the UK, Optogama in Lithuania, Lasertec in Japan, and so on; residential business mainly include Fujing Innovation, Jabil Skyway, Hengguang Optoelectronics, Nanjing Crylink, Jingyuan Optoelectronics, etc.
