单块环形ＹＡＧ激光器和片状放大器系统的窄带辐射振荡引言半导体泵浦激光器的发展产生了小型、高稳定、窄谱线激光器［１，２］。一系列科学和实际应用（高分辨率光谱学、非线性光学、周围介质的远距离诊断、物体速度和微小位移的遥测等）都要求在保持辐射良好的频率和空... Narrow band radiation oscillations in monolithic circular YAG lasers and chip amplifier systems Introduction The development of semiconductor pump lasers has led to the development of small, highly stable, narrow-line lasers [1,2]. A wide range of scientific and practical applications (high-resolution spectroscopy, nonlinear optics, long-range diagnostics of the surrounding medium, telemetry of object velocities and microdisplacements, etc.) are required to maintain a well-radiated frequency and empty ...
