Zenghu Lie inside the medium the intensity . is given by the sum of the two intensities ..(.) and .. (.). This is a reasonable approach for most lasers since the effect of spatial hole burning on the output power is smoothed out by atomic motion (gas lasers), energy migration, or axial multimode operation (scringe 发表于 2025-3-30 14:44:28
