Abstract: Lasing of quantum cascade lasers is demonstrated at a radiation wavelength of 8100 nm at room temperature. Analysis of oscillograms of optical pulses is used to determine dependence of mean and peak radiation intensities on current. A delay of turn-on of quantum cascade lasers is experimentally estimated at a level of two times higher than the lasing threshold to be greater than theoretically estimated delay by several orders of magnitude.

Keywords: Quantum Cascade Lasers (QCL), Peak Radiation Intensity, Optical Pulse, Laser Threshold, Interlevel Relaxation.
