本文报道了Yb3+、Ho3+掺杂钇钪镓石榴石在激光二极管激发下在1.2 μ m和3 μ m左右的激光振荡。在室温连续波激励下，1208 nm处的输出功率高达135 mW，相对于入射泵浦功率的斜率效率高达7.6%。准连续波激发导致2844 nm的激光发射，脉冲能量可达10 m.J。给出了激光的相关光谱数据，即寿命、吸收和发射截面，并给出了激发态吸收光谱。(C) 2000年美国物理研究所。[S0021 - 8979(00) 07909 - 3]。
We report on the laser oscillation of Yb3+, Ho3+-doped yttrium scandium gallium garnet around 1.2 and 3 mu m under laser diode excitation. At 1208 nm output powers of up to 135 mW and slope efficiencies up to 7.6% with respect to the incident pump power were achieved at room temperature under continuous wave excitation. Quasicontinuous wave excitation led to laser emission at 2844 nm with pulse energies up to 10 m.J. The laser relevant spectroscopic data, i.e., lifetimes, absorption, and emission cross sections are given and the excited state absorption spectrum is presented.
