Cr，Er:YSGG laser crystal used in medicine, scientific research, material processing fields


In Cr, Er: YSGG crystal, Cr3 + replaces GA3 + or SC3 + and Y3 + replaces Er3 +, which has the advantages of large size, small optical damage, high optical quality and low laser threshold. The laser crystal is usually pumped by flash lamp or laser diode. 970nm laser diode is the first choice to realize 2790nm Er, Cr: YSGG laser pump. It can directly excite Er3 + to its laser upper level, with high efficiency and low energy consumption. At present, to realize pulsed laser output, many methods are used to switch Q (such as acousto-optic, electro-optic, FTIR). Due to the particularity of laser wavelength, this laser is widely used in medicine, scientific research, material processing, military, and other fields.
