摘要
计算了厄米－高斯光束经Ｆ－Ｐ干涉仪反射和透射的多光束干涉光强值，给出了反射和透射的多光束干涉极大的条件．编程计算了上述反射和透射多光束干涉极大值依赖于基模束腰半径变化的关系曲线，通过比较发现，在多光束干涉极大条件下，基模（或低阶模）的反射和透射大于高阶模．这一研究结果。
Reflected and transmitted multiple beams interference intensity for Hermi Gauss beams incident on a F P interferometer are calculated,the conditions of reflected and transmitted multiple beams interference maximum are given.The curves of above mentioned reflected and transmitted multiple beams interference maximum vs the beam waist radius ω 0 of fundamental mode are calculated by programming.It is shown that,under the conditions of multiple beams interference maximum,the reflectivity and transmission of the fundamental mode (or lower order modes) are larger than for the higher order modes.This results could provide a new method for transverse mode selection in a laser.
