Abstract:
1. An optical system, including: a multipass optical amplifier including, a thin disk gain medium, a first reflective element optically coupled to the thin disk gain medium, a first parabolic reflector in optical communication with the thin disk gain medium and the first reflective element, a second parabolic reflector in optical communication with the first parabolic reflector, and a second reflective element in optical communication with the second parabolic reflector; a pump source operable to stimulate the this disk gain medium; a signal beam source to provide a signal beam of optical energy; and a chamber having first and second regions configured about the multipass optical amplifier and including a port that is operable to extract gas residing in the chamber, wherein the first region of the chamber includes the first parabolic reflector, the thin disk gain medium, and the first reflective element, wherein the second region of the chamber includes the second reflective element and the second parabolic reflector, wherein the second region of the chamber includes input and output optics, wherein the input optic is operable to receive the signal beam of optical energy and propagate the optical energy through the multipass optical amplifier to impinge the thin disk gain medium multiple times to impart gain on the signal beam before ejecting the optical energy through the output optic.
