Theoretical and experimental investigation of optical bistability in end-pumped Tm，Ho：YLF lasers

摘要: We demonstrate the strong optical bistability of a 2μm continuous wave Tm，Ho：YLF laser end pumped by 792nm fiber-coupled diode. The quasi-three-level rate equation theoretical model is given under consideration energy transfer upconversion and ground state reabsorption effects. bistable output predicted theoretically solving coupled equations mechanism analyzed. also studied experimentally. When crystal at 253K，the width region 1.6W jump power tujump point 82.5mW. results are in agreement with experimental results，showing that reasonable.
