| 摘 要： | 用提拉法生长了掺铬、钕的钆镓石榴石(Cr4+,Nd3+∶GGG)自调Q激光晶体。报道了室温下的吸收光谱和荧光光谱特性。分析了Cr离子浓度对光谱性质的影响。比较了Cr4+∶GGG,Nd3+∶GGG和(Cr4+,Nd3+)∶GGG晶体吸收光谱的关系。测量了(Cr4+,Nd3+)∶GGG晶体和Nd3+∶GGG晶体的荧光寿命,它们分别是33μs和250μs。实验表明,(Cr4+,Nd3+)∶GGG晶体是一种非常有潜力的自调Q激光晶体,可以实现大功率激光器的小型化和全固态化。

| Abstract: | The high-average-power solid-state-laser (HAP SSL) crystal (Cr4+,Nd3+)∶Gd3Ga5O12 (Cr4+,Nd3+)∶GGG] has been grown by the Czochralski method. The optical spectra of (Cr4+,Nd3+)∶Gd3Ga5O12 single crystals with 2at.% Nd and different Cr4+ concentrations were measured. The effect of Cr concentrations on, fluorescence lifetime and fluorescence peak wavelength of (Cr,Nd)∶GGG crystals were analyzed. The absorption spectra of Cr4+∶GGG, Nd3+∶GGG and (Cr4+,Nd3+)∶GGG crystal are compared. The fluorescent lifetime of (Cr4+,Nd3+)∶GGG and Nd3+∶GGG are 33 μs and 240 μs, respectively. This crystal may be potential materials for compact, efficient, high stability laser-diode-pumped passive Q-switched solid-state laser. |
