Operating and thermal characteristics of the most 
popular types of pulsed injection lasers (ILs) are presented; reasons 
for and mechanisms of the temperature dependence of their radiation 
power are briefly considered. The simplest methods of stabilization 
of the injection-laser power, based on control of the laser pumping 
depending on the ambient temperature, compensation for the temperature 
change in laser parameters, and maintenance of the laser-crystal temperature 
at a constant level are analyzed. As the most perfect, methods of 
thermostabilization of injection lasers based on the use of photoelectric 
feedback and methods based on the principle of discrimination of pulsed 
signals by the criterion of priority of their arrival are investigated 
in greater detail. Methods of protection of the laser crystal against 
thermal overloads and injection-current surges are considered briefly.
