Abstract
The analytical formulas of laser threshold,slope efficiency of a three-energy-level system are deduced from rate-equations of transitions.The absorption cross section of Er3+ ions in YAG crystal is calculated according to measured absorption spectrum.The characteristics of laser at 1.6μm wavelength are analysed.
