High-power laser diodes with emission wave length of 808 nm. II. Non-thermal mechanisms for limiting of radiated power

In the course of work [1] in this article the review of the non-thermal mechanisms limiting the output radiated power of laser diodes is presented. These mechanisms are separated into two groups: one group covers those related to the carriers’ accumulation in the waveguide layers of laser structure at the currents exceeding the threshold value. another group consolidates the mechanisms related to non-equilibrium distribution of electrons and holes in the active area of laser, caused by the significant shortening of carriers life times due to stimulated emission. The competition of thermal and non-thermal mechanisms of the optical power limitation is considered for the pulsed and continuous-wave injection pumping.
