One of the most effective and feasible ways of broadening the range of the output wavelength is using frequency conversion of non-linear Crystal under the condition of phase matching.

拓宽激光输出波长的范围最常用最有效的方法之一是利用非线性晶体在相位匹配条件下的频率变换技术。

Ice crystals are the main sources of graupels, which are produced mainly by auto conversion from ice crystal to graupel and a few grow by collection of ice crystals.

冰晶是霰的主要来源，而且也是霰生长的主要因素。初始的霰粒主要由冰霰自动转化生成，而较少由雨滴冻结生成。
