A Diode-Laser-Pumped Solid-State Laser for LIGO

拜尔集团的这项研究计划将通过激光开发直接支持LIGO项目；研究高功率运行的热效应；使用非线性晶体进行倍频。激光稳定和激光可靠性也将被调查。激光研制工作将完成13W半导体激光泵浦的Nd：YAG激光器的建造和测试。对热效应的研究将包括在干涉仪中对热效应进行数值模拟，以及测量光学元件中的散射、吸收和应力诱导的双折射。倍频研究将使用LBO、镁氧化物掺杂的LiNbate和周期性极化的LiNbate等材料来研究有效的倍频。

This program of research by the Byer group will directly support the LIGO project through laser development; studies of thermal effects from high power operation; frequency doubling using nonlinear crystals. Laser stabilization, and laser reliability will also be investigated. The work on laser development will complete the construction and testing of a 13-W diode-laser-pumped Nd:YAG laser. Studies of thermal effects will include both numerical modeling of these in interferometers, as well as measurements of scatter, absorption, and stress-induced birefringence in optical components. Research on frequency doubling will investigate efficient doubling using materials such as LBO, magnesium oxide-doped lithium niobate, and periodically poled lithium niobate.
