Abstract

The spectrum of a high power multielement laser array is narrowed using reflection feedback from an 100 μm etalon placed in front of the laser. The full width at half maximum (FWHM) of the laser array is reduced by a factor of 2 with only 6% power loss. This reduction in FWHM is useful for optical pumping of alkali metals in the presence of high density buffer gas.
