Paper Abstract

As a novel cw hybrid laser, the lasing wavelengths lie in the near-IR range and for in the transparency window of the terrestrial atmosphere, diode pumped metastable rare gas lasers (DPRGLs) can be considered as a beam conversion system that produces a high-quality laser beam by passing a diode laser with poor beam quality through the rare gases medium at room temperature. In this paper, a numerical model is set up to describe the kinetic processes and the laser amplification, based the five-level structure, in DPRGL amplifier (DPRGA) system. Influences of the pump power and the cell length on the output laser are simulated and discussed. Such a master oscillator power amplifier (MOPA) system is very promising in achieving high output power for low power DPRGL radiation.
