Paper Abstract

We describe the design and performance of highly stable and high power Nd:YAG laser system for the interferometric gravitational wave detectors. The frequency of a diode-pumped Nd:YAG laser is stabilized by using a high finesse optical cavity, and its frequency noise is reduced to as low as 1.5 mHz/(root)Hz. Using a high power lamp-pumped ring Nd:YAG laser, single frequency output power of 4 W is obtained, and the injection locking is realized by using a diode-pumped laser as a master laser. We also show the design of high power single frequency diode-pumped Nd:YAG lasers.
