The studies of the spectral and dynamic characteristics of quantum-cascade lasers emitting in the long-wave infrared range are presented. It has been shown that lasers with a short resonator (~ 1 mm) generating frequency combs in a very wide spectral range. The dynamics of the the frequency comb generation mode was studied. It is shown that the intensity of the longitudinal modes of laser generation changes during the pump pulse. At the same time, simultaneous generation of all longitudinal modes of the frequency comb during flat part of the pumping pulse is observed.
