The dynamics of laser generation in single-mode semiconductor (1060 nm) emitters microbar under sub-ns pulse pumping

The operation of single-mode semiconductor (1060 nm) emitters microbar without optical coupling between the stripes was studied. The operation in the regime of a single relaxation optical pulse with a duration of 140 ps and power up to 3 W was demonstrated. The beam diagram of the microbar corresponded to the pattern of a single-mode emitter.
