WebJan 21, 2024 · The reflectance is a periodic function along two directions. So, one can indeed think of it as two diffraction gratings, but instead of a multiplication of their transmission functions (or reflectance functions), we have the addition of their transmission functions. WebGratings are used in these lasers to control and narrow the lasing wavelength. Molecular lasers, operating both pulsed and continuous-wave (cw) in the infrared, typically have their output wavelength tuned by Littrow-mounted gratings. High efficiency is obtained by operating in the first order at diffraction angles >20°. mother angelica classics live
