Abstract
The principles of use of gratings as laser wavelength-selective end reflectors are reviewed A useful output beam can be derived from a grating's zeroth-order reflection This beam moves when the grating is rotated to select various laser wavelengths, but can be made stationary by the addition of auxiliary mirrors The grating-mirror combination has been applied to a CO(2) laser in the in and to a dye laser in the visible

Theoretical and Experimental Investigation of a New Type of Blazed Grating

TL;DR: In this article, a rigorous electromagnetic theory of diffraction of light by blazed lamellar gratings has been developed, which is applied to calculate the diffracted power distribution of four gratings (R1 − R4) whose grooves have the following depths and widths (b,l) in units of grating period a: (0.433, 0.750), ( 0.667), (0.,250, 0.,500), and (0 0.400).
