摘要

CO气体分子发射激光需要在低温(液氮温度附近)时才容易实现。为在常温条件下实现CO的激光输出

采用横向激励大气压(TEA)脉冲放电的方式对CO气体分子在室温条件下的红外发光辐射性能进行了实验研究。在实验所限定的参数条件下

没有获得FO波段激光辐射

仅实现了FB波段的激光输出。典型的指标为:电光转换效率1％

中心波长5.3 m

辐射能量0.22 J

辐射脉宽(FWHM)700 ns

相当于辐射的峰值功率达到0.3 mW左右;当以500 Hz放电脉冲重复频率运转时

常温条件下还获得了大于百瓦量级的高平均功率辐射输出。

Abstract

Lasing from CO molecular is easy to realize about liquid nitrogen temperature

however

normally it is hard to lasing at room temperature. To solve this problem

experimental research on CO molecular lasing at room temperature is carried out with TEA technology

the results show that

at some limited conditions

there is no FO band lasing but just FB doing

The typical electric optical conversion efficiency is 1%; center wavelength at 5.3 m; pulse energy 0.22 J; FWHM 700 ns and peak power 0.3 mW. When the pulse repetition rate is 500 Hz

100 watts average power is obtained at room temperature.
