Abstract

See full text

Apparatus and methods that enable the suppression of amplified spontaneous emission (ASE) and prevention against parasitic lasing in cryogenically-cooled laser amplifier systems, thus allowing sustainable extraction efficiency when increasing the pump power and suitable for large-scale, high average-power laser systems employing large-aperture gain media. A gain medium having a known index of refraction for operation in an evacuated, cryogenic environment includes an ASE-absorbing epoxy composition on the perimetrical edge of the gain medium, wherein the epoxy composition has an index of refraction that substantially matches the index of refraction of the gain medium.
