| 摘 要： | 介绍几种主动式产生近似无衍射光的方法,并用谐振腔理论进行分析和模拟.可以发现,利用轴棱锥设计的谐振腔具有结构简单、转换效率高等特点;而采用腔内振幅滤波的谐振腔,则不需要复杂的光学元件和特别的准直技术;用LD泵浦的Nd∶YAG激光器输出近似无衍射光,可以有效地提高泵浦光效率和激光输出能量.

| Abstract: | Several active methods for generating approximate non-diffracting Bessel beams are introduced by using resonator theory to analyze and simulate. We find that axicon-based resonator has simple structure and higher conversion efficiency;resonator with internal amplitude filter does not require complex optical element and special alignment technology;and the advantage of generating approximate non-diffracting Bessel beams by using a diode pumped Nd∶YAG laser is sufficient to improve output powers and efficiencies. |
