摘要：
The investigation of the gains and threshold currents is carried out for several quantum well lasers of differing potential well shape. The theoretical threshold current density as a function of laser cavity length compares very well with the result obtained from experiments. The gain and photon density as a function of time are reported for several GRIN-SCH potentials of differing shape. The gain of multiple quantum well potentials shows a narrower spectrum than single quantum well potentials. The oscillation frequency of a laser when it is excited by short current pulse is linear with the square root of the power, in agreement with experiments.
