Patent ID: 7648290

Claim:
A microchip laser package, for use with a fiber-coupled pump diode, comprising: a first tubular housing having a longitudinal axis for receiving a ferrule holding an input fiber, which is optically coupled to an output of the fiber-coupled pump diode, wherein the first tubular housing has a first flat mating surface at an outermost end thereof, the first flat mating surface being oriented generally perpendicular to the longitudinal axis; a second tubular housing for receiving a monolithic microchip laser, wherein the second tubular housing has a second flat mating surface at an outermost end thereof, the second flat mating surface being oriented generally perpendicular to the longitudinal axis; and wherein the first tubular housing and the second tubular housing abut each other at their first and second flat mating surfaces, respectively, in a non-overlapping configuration adjusting the lateral position of the second tubular housing relative to the longitudinal axis of the first tubular housing; front focusing optics, disposed in first or second tubular housings, at a predetermine distance from a first end of the monolithic microchip laser, a laser head mount for supporting the second tubular housing; and temperature controlling means for controlling the temperature of the laser head mount; wherein an end of the first tubular housing is attached to an end of the second tubular housing such that pump light from the fiber-coupled pump diode is focused onto a first end of the monolithic microchip laser by means of the front focusing optics.
