    Abstract

    Due to the high beam divergence of standard laser diodes (LDs), these are not suitable for wavelength-selective feedback without extra optical elements. This letter reports on first prototypes of compact tunable LDs with wavelength-selective feedback via a so-called abnormal reflecting mirror of a low divergent beam coming from a special LD, emitting through the substrate. With this setup, tunable narrow-band (<0.7 nm) lasing is observed showing good temperature stability. Tuning over a range of 5 nm at a maximum power of 0.2 W was demonstrated.
