Abstract
A diode-pumped microlaser in accordance with the present invention includes a diode pump, a first lens, a second lens and a laser glass. The diode pump generates an input pump beam. The first lens and second lens manipulate the pump beam by collimating the pump beam in focal planes that are perpendicular to each other. The laser glass receives the manipulated pump beam from the second lens and converts the pump beam into a laser beam. The laser glass is further doped with predetermined amounts by weight of Erbium and Ytterbium to ensure that an output laser beam with an eyesafe wavelength is generated. The microlaser further includes a passive Q-switch made of a Cobalt-spinel material, which receives the output laser beam and generates laser pulses using passive switching techniques, independent of any external temperature control. This configuration allows the microlaser to function as a laser rangefinder over extended temperature ranges in a manner that is eyesafe to the user.
