Comprehensive Four-Level Laser Model With Power Conservation Part II: Laser Amplifiers, Resonators, and System Considerations

In this paper, the second of a two-part manuscript, we extend the comprehensive kinetics model of Part I to treat four-level solid-state amplifiers and resonators, followed by the presentation of a detailed systems model that preserves power conservation throughout. We believe that this laser systems model is the first to allow an end to end description of the power flow in a solid-state laser while maintaining power conservation, can easily be extended to include quasi-three-level and other laser kinetics schemes, and will provide a very useful tool to physicists and engineers engaged in the design and optimization of solid-state laser systems.
