| Abstract: | We develop a separate 1319 and 1338 nm Nd:YAG laser system with a blazing grating (600 lines/mm). The resonator of this system
has a Littrow grating configuration and a highly reflective mirror, in which the zero-order diffraction of the grating acts
as the laser output. By virtue of the wavelength-dependent reflectivity of the grating, a single-wavelength laser at 1319
nm or 1338 nm can be realized. In view of the laser rate equations and using the distribution of the blazing grating, we analyze
the oscillation conditions providing single-wavelength laser operation in the system. |
