１μｍ波段的新晶体激光器目前在激光晶体中，能在室温和各种泵浦方式下于１．０６～１．０７μｍ产生低阈值受激辐射的基本激活剂唯有Ｎｄ２＋离子［１］。它的１μｍ受激辐射（由激光末级能态的能量约为２０００ｃｍ－１左右的斯塔克跃迁通道间的四能级系统激励）是大多... New crystal lasers in the 1 μm band are the only basic activators capable of generating low-threshold stimulated radiation at 1.06 to 1.07 μm at room temperature and in various pumping modes at present in the laser crystal [1]. Its 1μm stimulated emission (by the end of the laser energy state about 2000cm-1 Stark transition between the four-level channel excitation system) is the most ...
