在混合晶体硫化镉和硒化镉中第一次获得了激光作用。硫化镉的辐射光谱在绿色区,硒化镉则在红色区。麻省理工学院林肯实验室的赫维茨(C. E. Hunvitz)说,改变混合晶体的成分,就能选择所需的辐射颜色。用电子束激励时,激光器可以在绿色与红色之间的任何要求的波长上辐射。当输出功率为20瓦时,装置的效率为15%。
We demonstrate a tunable wavelength-locked seed laser source with high-frequency stability to realize the precise measurements of global atmospheric wind field. An Nd:YAG laser at 1 064 nm is used as the master laser (ML). Its frequency is locked to a con
