Abstract:
1. An optical gain architecture comprising: a pump source operable to produce light at a pump wavelength along an optical path; a pump aperture operable to receive the light at the pump wavelength; a gain region disposed along the optical path and including a gain element operable to amplify light at a laser wavelength, wherein the gain region is characterized by a first side intersecting the optical path, a second side opposing the first side, a third side adjacent the first and second sides, and a fourth side opposing the third side; a dichroic section disposed between the pump aperture and the first side of the gain region, wherein the dichroic section is characterized by low reflectance at the pump wavelength and high reflectance at the laser wavelength; a first cladding section proximate to the third side of the gain region; a second cladding section proximate to the fourth side of the gain region; a second dichroic section disposed along the optical path proximate to the second side of the gain region, wherein the second dichroic section is characterized by a high reflectance at the pump wavelength and a low reflectance at the laser wavelength; and a third cladding section proximate to the second dichroic section.
