Although the 532 nm (green) wavelength has the lowest absorption in water,generating the 532 nm (green) or 355 nm (ultraviolet) wavelengths with harmonic single crystals from 1064 nm laser pulses reduces the laser pulse energy output by a factor of two or more due to the conversion process and to associated inefficiencies.
答
虽然532 nm（绿色）波长在水中吸收为最低,从1064 nm的激光脉冲中产生带谐波单晶的532 nm（绿色）波长或355 nm(紫外线)波长,鉴于转换过程及相关的低效率,其激光脉冲能源的输出会由于除以2或更大的系数而降低.
