Annotatsiya

The main parameters of a heterojunction laser diode, such as the emission frequency spectrum (optical modes), threshold current, output radiation power, and operating efficiency, are considered. A simplified formula for the radiation intensity of a heterostructure laser is obtained. It is shown that, due to reflection from the ends, the light repeatedly passes through the active region and is predominantly amplified by stimulated emission. A standing wave is established inside the laser diode with an integer number of half-waves between the end surfaces.
