Аннотация:A method is proposed for measuring the degradation rate of a high-power continuous-wave laser diode with a wide contact by monitoring the state of its heterostructure every fifty hours of operation. The number and structure of laser generation channels is used as a controlled parameter. The mechanism of degradation of the laser diode structure, which is manifested in the time dependence of the number of generation channels, is considered.
