window cooler meaning in English

窗式冷却器

Absolute distribution of laser beam intensity is gotten from comparative distribution . the absorption coefficient of material is calculated by measuring transmissive ratio . the influences on temperature increment , stress and phase of laser beam are computed with different time , window cooling , window rotating , shape and material of window , distribution of intensity
由近场光斑相对分布得到其绝对分布，测量窗口透过率，求得材料的吸收系数，在此基础上计算了出光时间长短、窗口有无冷却、是否旋转、窗口材料及面型、光强分布形式对窗口温升、应力和光束位相的影响。
