Patent ID: 8811439

Claim:
A laser system, comprising: a single member heat exchanger having a cylindrical bore extending through the heat exchanger, the bore comprising a first section with a first cylindrical inner wall having a first diameter and a second section with a second cylindrical inner wall having a second diameter greater than the first diameter; a carrier comprising a cylindrical disk-shaped base having a contiguous cylindrical surface and a horseshoe-shaped mount having a curvilinear horseshoe-shaped external surface that projects from the base, the mount having a pedestal area that defines a plane that extends in a direction of an axis of the bore and on which a semiconductor gain chip is mounted, the -carrier projecting into the bore and the external surface of the mount being in contiguous surface contact for heat transfer with the first diameter inner wall and the cylindrical surface of the base being in contiguous surface contact for heat transfer with the second diameter of the inner wall; and a lens mounted on the heat exchanger and covering the bore.
