Abstract
The temperature dependence of the threshold current in electron-beam-pumped (EBP) lasers using p-type GaAs (2 × 10l8 cm−3) at 27 KV is theoretically determined, taking into account the inhomogeneous distribution and the temperature dependence of the lifetime of the excess carriers. The computed dependence is found to be in excellent agreement with the experimental observation. A comparison is then made of the result with results obtained under different assumptions to confirm positively that, in the study of the performance of these lasers, the above two features cannot be ignored.
