LASER AMPLIFIER

摘要

PROBLEM TO BE SOLVED: To provide an amplifier enabling an efficient laser operation even in an excitation in comparatively low intensity such as a semiconductor laser. SOLUTION: A method and a device for amplifying a laser having high efficiency are provided by cooling an Ytterbium-added YAG crystal excited by the semiconductor laser at an arbitrary temperature between an absolute temperature of 8K to 230K.
