A laser amplifier module having an enclosure includes an input window, a mirror optically coupled to the input window and disposed in a first plane, and a first amplifier head disposed along an optical amplification path adjacent a first end of the enclosure. The laser amplifier module also includes a second amplifier head disposed along the optical amplification path adjacent a second end of the enclosure and a cavity mirror disposed along the optical amplification path.

Method and system for compact efficient laser architecture

A composition of matter is provided having the general chemical formula K(H,D)P(O,O), where x&#x3c;0.998 or y&#x3e;0.002, and x+y&#x2248;1. Additionally, a method of fabricating an optical material by growth from solution is provided. The method includes providing a solution including a predetermined percentage of (H,D)O and a predetermined percentage of (H,D)O, providing a seed crystal, and supporting the seed crystal on a platform. The method also includes immersing the seed crystal in the solution and forming the optical material. The optical material has the general chemical formula K(H,D)P(O,O), where x&#x3c;0.998 or y&#x3e;0.002, and x+y&#x2248;1.

An optical gain architecture includes a pump source and a pump aperture. The architecture also includes a gain region including a gain element operable to amplify light at a laser wavelength. The gain region is characterized by a first side intersecting an 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. The architecture further includes a dichroic section disposed between the pump aperture and the first side of the gain region. The dichroic section is characterized by low reflectance at a pump wavelength and high reflectance at the laser wavelength. The architecture additionally includes a first cladding section proximate to the third side of the gain region and a second cladding section proximate to the fourth side of the gain region.
