| 摘 要： | 本文基于随机激光的时域理论,研究了飞秒脉冲抽运下二维随机激光的辐射特性,并着重讨论了抽运脉冲的峰值强度、脉宽和脉冲波形对辐射光时域波形的影响.结果表明, 辐射光的时域波形强烈依赖于抽运光脉冲的参数,通过调整抽运方式可以控制辐射光的输出波形.数值模拟结果为研究随机激光输出波形的可控性技术提供了理论依据.

| Abstract: | The emission property of two-dimensional random laser under femtosecond laser pumping is theoretically investigated by using the time-dependent theory. The effects of peak intensity, duration and shape of a pumping pulse on temporal property of the random laser emission are discussed. Results show that the behavior of random lasing depends strongly on the pumping process, thereby one can control the random laser output waveshape through modifying the pumping parameters. The present work can provide more guidance for the controllability of random laser. |
