| 摘 要： | 由于自发辐射噪声的涨落，CO2激光器的脉冲峰值强度与时间延迟密切相关。理论和实验研究发现，对于典型的B类CO2激光器，在损耗调制情况下，当脉冲峰值出现在最低腔损耗t0之前时，初始自发辐射噪声越大，相对于阈值点的第一个渡跃时间tFP越小，对应的峰值强度越小；当脉冲峰值出现在最低腔损耗t0之后时，初始自发辐射噪声越大，相对于阈值点的第一个渡跃时间tFP越小，对应的峰值强度则越大。 |
| 关 键 词： | 自发辐射噪声 B类激光器 第一个渡跃时间 |

| Abstract: | The intensity of CO2 laser was correlated with the time delay by reason of the spontaneous emission fluctuation. The experimental and theoretical results show that when the laser peak present before the minimum switched loss, the larger the initial spontaneous emission, the shorter the time delay, because of and the intensity of laser peak is smaller in a B-class CO2 laser. When the laser peak present after the minimum switched loss, the time delay is longer because of the larger initial spontaneous emission, the intensity of laser peak is also larger. |
| Keywords: | spontaneous emission noise b-class laser first transition time |
