pure-tone pulse

The processes of thermal conduction in Raman cell pumped by laser pulse was simulated by computer. The behavior of stimulated Raman scattering pumped by train pulse doubled YAG laser in pure oxygen and O 2/ He mixture was studied experimentally.

对氧气的受激拉曼散射池的热传导过程进行了数值模拟计算，实验研究了序列脉冲倍频YAG激光器泵浦情况下氧气受激拉曼散射的热效应问题。

Taking the short pulse as an ideal delta function on time scale, we find that the radiation field pattern is just of the "pure" waveguide modes if the resonance frequency equals as integral times as radio frequency.

将短脉冲理想化为时间上的δ函数，可以发现当辐射频率正好等于用来调制电子束的射频的整数倍时，辐射模式表现为纯的波导本征模，此时辐射功率最强。
