Line narrowing and enhanced efficiency of an HgBr laser by injection locking

Abstract

The results of HgBr laser injection locking experiments are presented. The output energy and spectrum of an injection locked HgBr laser has been measured versus injection wavelength. When injection locking near 502 nm, the narrow band (0.05-nm FWHM) output energy was 30% higher than the broadband HgBr laser output. The wall plug efficiency of the injection locked HgBr laser is 1.3%.
