Third, laser crystals emitting at UV and visible regions for color displaying and optical lithography.
面向全色显示、光刻等应用的蓝绿紫和可见光激光晶体；

The majority of known tunable UV sources were complicated devicescomprising some tunable laser in visible region and subsequent nonlinear frequency conversion.
以前的可调谐紫外激光器是基于可见光区域的可调谐激光，经过非线性频率变换得到。 结构复杂、可靠性差。
