fundamental transverse mode meaning in English

横向基本振荡模
基横模

Compared with the traditional lamp - pumped solid - state lasers , the diode - pumped solid - state lasers ( dpssls ) have many advantages such as high efficiency , long lifetime , all - solid - state , small size and little heat effect , etc . of many kinds of dpssls , laser diode ( ld ) end - pumped nd : yag laser plays an important role and has been found wide applicatins in industry , mainly because of its good mechanical and optical properties of nd : yag crystal and good mode matching to output a fundamental transverse mode
与传统的灯泵浦相比，激光二极管泵浦固体激光器( dpssls )具有高效、长寿命、全固化、热效应和体积小等优点。在众多的dpssls中，激光二极管( ld )端面泵浦nd ： yag激光器在工业中起着重要的作用并得到了广泛的运用，这主要归因于nd ： yag晶体具有良好的机械和光学特性，而且端面泵浦具有良好的模式匹配，能获得基横模激光输出。
