Laser cavity for optical pumping of laser active material - uses light source to provide partial, alternating diffusely reflected and imaging reflected radiation

摘要

A laser cavity (10) has optical pump laser active material (12) and a light source (11) which is made partly, alternatingly, diffusion reflective and image refective by a reflector (10) of elliptic, parabolic or other cross-section which considerably increases the efficiency and homogenity of the laser. ADVANTAGE - Guarantees high emission efficiency and good homogenity.
