Abstract

Apodized apertures (AAs) are used in laser physics for following purposes:1–3 avoiding hard-edge Fresnel diffraction ripples in beam cross-sections; generating diffraction-limited beams without side lobes, diminishing beam divergence in single-mode lasing by using AAs inside the resonator; increasing second-harmonic conversion efficiency; compensation of pumping inhomogeneity in active elements; experiments of interaction of laser radiation with matter, which require Gaussian or super-Gaussian spatial intensity profiles, etc.
