Results of studying stripe quantum cascade lasers emitting at room temperature in the spectral range of 4.8 µm are presented. Power characteristics and turn-on dynamics of the lasers upon pulse pumping are studied. The performed investigations demonstrate the presence of a significant heating of the active region during the pump pulse.
-1 Представлены результаты исследований вертикально-излучающих лазеров на основе субмонослойных квантовых точек InGaAs с оксидной апертурой диаметром ~ 1 mum. Продемонстрирована возможность обострения выходных оптических импульсов до 50-100 ps при накачке электрическими импульсами длительностью 10-100 ns с частотой повторения 10-100 kHz.
