| 摘 要： | 本文从理论与实验两方面讨论脉冲激光入射时法布里-珀罗（FP）腔的透射特性。结果表明：FP腔的输出波形分三个明显阶段：建立阶段、稳定阶段及衰荡阶段。建立阶段表示激光注入、稳定阶段表示腔内信号达到最大值、衰荡阶段则表示外部激光注入停止。衰荡阶段的衰荡时间与腔的振幅衰减系数有关。 |
| 关 键 词： | 法布里-珀罗腔 脉冲激光入射 衰荡 |

| Abstract: | The transmission characteristic of Fabry-Pérot cavity with pulsed laser injection is investigated theoretically and experimental demonstration.It is demonstrated that there are three phases： build-up,stability,and ring-down phase.Build-up phase shows the injection of light,stability expresses that the cavity reaches a maximum,and ring-down phase denotes that the injection of light is ceased.The decay shows an exponential behavior,its decay time called cavity ring-down time is related to the fractional amplitude attenuation factor by the cavity mirrors and by absorption and scattering in the cavity medium. |
| Keywords: | Fabry-Pérot cavity pulsed laser injection ring-down |
