测量了Cr∶Nd∶GSGG晶体从 - 70℃到 +80℃温度下的荧光发射光谱和荧光寿命 ,计算了该晶体在不同温度下 1 .0 61 μm受激发射截面 ,获得在此温度变化范围内受激发射截面随温度的线性变化关系
The fluorescence emission spectra and fluorescence lifetime of Cr:Nd:GSGG crystals at -70 ℃ to + 80 ℃ were measured. The calculated cross section of the crystal at the different temperature of 1.61μm was obtained, and the temperature range Within the stimulated emission cross section with the linear relationship between temperature changes
