摘要

我们提出了一种新型的稳定消光虹膜，用于调q工作(10 - 20 ns)和连续波工作(10 W/cm2)中峰值强度超过700 MW/cm2的激光器。这种虹膜可以用来抑制光束中的衍射不均匀性，这种不均匀性会导致激光元件的自聚焦和破坏。由于其特殊的吸收特性，这些虹膜可以在宽的光谱间隔(0.6-3.5 μm)内使用。

Apodizing apertures for visible and IR lasers

We propose a new type of stable apodizing iris for lasers with peak intensities above 700 MW/cm2 in Q-switched operation (10–20 ns) and 10 W/cm2 in cw operation. Such irises can be used for suppressing the diffraction inhomogeneities in light beams, which cause self-focusing and destruction of laser elements. Because of their particular absorptive characteristics, these irises can be used over a wide spectral interval (0.6–3.5 μm).
