Paper Abstract

Red-emitting diode lasers currently do not offer a small spectral linewidth, which is required in a variety of applications like spectroscopy, interferometry and holography. We will present details of our work on diode lasers with internal surface DBR gratings. These DBR lasers exhibit effective operation of the gratings at four different lasing wavelengths from 632.2 nm to 638.1 nm. 30 μm wide DBR lasers obtain a spectrally stabilized optical output power of 250 mW in pulsed operation. We estimate the reflectivity of the rear grating to exceed 60%.
