Based on the nonlinear paraxial equation and b - t theory, a differential equation, which describes the small - scale self - focusing in gain ( loss ) media has been derived. the change rule of the maximal gain frequency, cutoff frequency and integral exponential gain have been analyzed approximately
我們首先從非線性近軸波方程出發,基於b - t理論的思想,在考慮了介質的增益(損耗)特性的情況下,推導得出了小尺度自聚焦所滿足的微分方程,並通過近似方法分析了最大增長頻率、截止空間頻率及積分指數增益等的變化規律。It is proved by experiment that the linear temperature distribution, which generates linear wavelength spread of the output beams from a ld bar, can be obtained by introducing a temperature gradient heat sink and the output beams can be focused into a relative small spot by using the czerny - turner beam combining system
本文探討了利用溫度控制波長的原理,提出了溫度梯度熱沉的初步設想,及耦合光學系統的設計。初步實驗的結果證明利用czerny - turner光束耦合系統,可以改善慢軸上的光束質量,將光束聚焦到較小的尺度。
