High-power spatially single-mode diode lasers at 15xx nm wavelengths are of interest for Light Detection and Ranging (LIDAR) at eye-safe wavelengths, as pump lasers for Raman and rare-earth doped fiber amplifiers as well as for material processing. A cost-efficient way to realize high-power in combination with high-brightness is the tapered resonator concept. We demonstrate InGaAsP/InP based diode lasers and tapered amplifiers with fast axis far fields of 36° FWHM and wavelengths around 1550 nm which were grown by MOCVD. From processed broad area lasers with 2mm resonator length and 100µm stripe width and 1mm long ridge-waveguide lasers, parameters for the logarithmic gain model are evaluated.
