报道了（Ｃｒ４＋ ， Ｙｂ３＋ ）ｖＹＡＧ晶体的吸收光谱和荧光光谱特性。在室温下， （Ｃｒ４＋ ， Ｙｂ３＋ ）ｖＹＡＧ晶体在９３７ ｎｍ 和９６８ ｎｍ 处存在两个吸收带， 能与ＩｎＧａＡｓ激光二极管有效耦合； 而且在１０３０ ｎｍ 处有一Ｃｒ４＋ 吸收峰， 可以实现对Ｙｂ３＋ 的自调Ｑ激光输出。（Ｃｒ４＋ ， Ｙｂ３＋ ）ｖＹＡＧ晶体的荧光光谱与Ｙｂ３＋ ｖＹＡＧ晶体一样， 发光中心也是位于１０２９ ｎｍ ， 但其强度比Ｙｂ３＋ ｖＹＡＧ 晶体的要低。（Ｃｒ４＋ ， Ｙｂ３＋ ）ｖＹＡＧ晶体和Ｙｂ３＋ ｖＹＡＧ晶体的荧光寿命分别为０．３ ｍ ｓ 和１．４ ｍ ｓ。因此双掺Ｃｒ４＋ 和Ｙｂ３＋ 的ＹＡＧ晶体将有可能成为一种自调Ｑ激光晶体， 从而实现固体激光器的小型化， 全固化
The absorption and fluorescence spectra of (Cr4 +, Yb3 +) vYAG crystals have been reported. At room temperature, (Cr4 +, Yb3 +) vYAG crystals have two absorption bands at 937 nm and 968 nm, which can be effectively coupled with InGaAs laser diodes. Moreover, there is a Cr4 + absorption peak at 1030 nm, Laser output. Fluorescence spectra of (Cr4 +, Yb3 +) vYAG crystals are the same as those of Yb3 + vYAG crystals. The emission center is also at 1029 nm, but its intensity is lower than that of Yb3 + vYAG crystals. The fluorescence lifetime of (Cr4 +, Yb3 +) vYAG crystals and Yb3 + vYAG crystals are 0.3 m s and 1.4 m s, respectively. Therefore, YAG crystals doped with Cr4 + and Yb3 + doping will become self-Q-switched laser crystals, which will make miniaturization and full curing of solid-state lasers possible
