OPTIMIZATION OF THE GALLIUM ARSENIDE INJECTION LASER FOR MAXIMUM POWER OUTPUT.

Abstract

The operating temperature of an injection laser is determined by the difference between the electrical input power and the coherent light output power, and by the details of heat conduction away from the active region. Since the efficiency of the coherent light generation is a decreasing function of temperature, a maximum exists in the curve of output versus input power. A mathematical model of the injection laser is employed to investigate how this maximum output power varies as a function of several design parameters of the injection laser. The optimum design is presented for the case of continuous operation in a 77K environment and discuss pulsed operation of low-duty cycle in a 300K environment.
