【摘要】 <正> 一、隐花菁染料调Q器件的动态输出特性 隐花菁调Q器件具有阶梯状的动态输出（如图1-所示）,即从动态阈值W₀起,逐渐增加输入能量,输出能量基本不变,直到输入能量达到W₁器件输出两个能量大致相等的脉冲为止,这时输出能量跃增一倍。原则上说,若光泵能量继续增加,则输出能量将随脉冲个数的增多而成倍增长。W₀到W₁称单脉冲区。在其他条件不变时,若光泵效率下降,动态输出曲线仅仅向右平移（如图1中虚线所示）,输出能量并不发生变化。因此若在单脉冲区的固定输入能量W下工作,则在相当更多还原

【Abstract】 The experimental investigations on Q-switching of a ruby laser system by cryptocyanine are reported: 1) The dependence of output characteristics on dye concentration and other parameters of the laser cavity, 2) the dependence of output energy on temperature and solvent of the dye, 3) the influences of temperature, solvent and impurity content on the optical bleaching of the dye solution. Theoretical analysis and numerical tests are made for the third problem on the basis of the experiments.更多还原
