90 mW 660 nm distributed feedback lasers

Abstract

High efficiency single spatial and spectral mode, 662 nm wavelength distributed feedback lasers have been fabricated from a GaInP/AlInP laser structure. Output powers of up to 90 mW at room temperature were achieved without any spectral mode jumps. These devices should be useful for short and/or visible wavelength applications that require spectral mode stability, such as spectroscopy, interferometry, and high-density optical storage.
