High-power pulsed hybrid semiconductor lasers emitting in the wavelength range 900-920 nm

High-power hybrid semiconductor lasers-thyristors (λ = 900 - 920 nm) consisting of thyristor crystals soldered in series with an integrated semiconductor laser with three emitting sections are studied. A monolithic laser-thyristor with three emitting sections is used as a reference sample. The output power of the triple monolithically integrated laser-thyristor is ≈120 W at a turn-on voltage of 18 V. The turn-on voltage of a hybrid laser-thyristor with three emitting sections is 28 V, and the peak output power reaches ≈170 W. © 2021 Kvantovaya Elektronika and IOP Publishing Limited.
