Влияние разогрева активной области на динамические и мощностные характеристики квантовых каскадных лазеров, излучающих на длине волны 4.8 μm при комнатной температуре

Abstract

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.
