高功率激光在克尔介质中传输的低频随机位相噪声

Low Frequency Random Phase Noises of High Power Laser Propagating in Keer Media

当高功率激光在克尔介质中传输时,低频随机位相噪声可以用高斯函数来描述,应用BT理论对低频随机位相噪声对光传输的影响进行了研究,低频随机位相噪声使功率增益谱低频部分的曲线产生了起伏,使中高频的振荡峰值明显增高,并且峰值向高频方向移动.

When high power laser propagates in Keer media, The phase noises at the low frequency can be described by a Gaussian function?The impacts of low frequency random phase noises on the propagation of light beams in Keer media have been studied with BT theory. The ripples are shown in the power gain spectrum and the oscillating peak value at the middle and high frequency rises considerabely. The peak value of the curve shifts integrally towards high frequency.
