Abstract
Pulsed 910 nm laser sources based on triple tunnel-coupled AlGaAs/InGaAs/GaAs heterostructures were developed and studied. High fill-factor (96%) microbars with $3\times 800\ \mu \mathrm{m}$ aperture were fabricated and studied under pumping by high-current pulse source (up to 750A/130ns/1kHz). Peak optical power up to 1150W at 25°C and 905W at 75°C were demonstrated.
