Apodized Apertures For Infrared And Visible High-Power Lasers
Year: 1989 Journal: Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE Vol: 0965 Pages: 25-25 Publisher: SPIE
Abstract
Simple apodized (soft) apertures (AA) were fabricated for use in laser physics to avoid hard-edge Fresnel diffraction in the beam spatial-intensity profile. These AA of ≈ 2-45 mm diameter have approximately Gaussian and super-Gaussian transmission function in the visible and infrared band. They have high threshold for intensity damage.
