【摘要】 实验研究了脉冲TEA CO₂激光泵浦NH₃分子系统的六条FIR激光谱线。测量了不同的泵浦能量、气体压强及泵浦吸收率对FIR激光输出能量的影响。结果表明:1,相应于最大FIR激光输出的最佳压强随泵浦失谐量的增大而增加;2,最佳的FIR激光输出不是产生于泵浦吸收率达100％的压强,而是在吸收率约90％左右的压强。更多还原

【Abstract】 Six FIR laser lines produced by a pulsed TEA CO₂ laser pumped NH₃ system have been studied experimetally. The dependence of FIE laser output energy upon the pumping energy,the pressure of molecular gases and the absorbability to pumping energy have also been measured. It has been shown that,firstly, the optimum pressure corresponding to a maximum FIB laser output increases proportionally to the increment of pumping frequency offset, and secondly, the maximum FIB laser output is observed under the pressure at which the absorbability to pumping energy is just about 90% instead of 100%.更多还原
