摘要：

We explore the full parameter space for laser operation and compile guidelines for building improved Ge lasers, especially for continuous wave applications. We present laser emission from p-type Ge lasers with small volumes at high repetition rates and with inter-contact distances as low as 750 mu m The emission is analyzed as a function of the current-voltage characteristic. The Poisson equation is solved to determine the electric field distribution and two new laser designs are presented. (C) 1999 Elsevier Science B.V. All rights reserved.
