Abstract
A cone laser-gain module including a pump-light source, a laser rod, and a cone structure, is provided. The cone structure, including a large and a small cone aperture connected by cone axis, is configured to accommodate the laser rod parallel to the cone axis and concentrate the pump light toward the laser rod. The pump light enters the cone structure from a large cone aperture. The laser rod is configured to absorb the pump lights to generate a laser light along a laser-emission axis parallel to the laser-rod axis. In particular, the pump lights, some of which diverge and initially miss the laser rod, are reflected and concentrated on the laser rod by an inner surface of the cone structure. A cone laser amplifier and a cone laser oscillator utilizing single or cascaded cone laser-gain modules are also provided.
