Theoretical modeling and design of a Tm, Ho:YLiF↓(4) microchip laser

摘要

We present theoretical modeling that makes it possible to compute the output characteristics of a laser-pumped codoped Tm, Ho microchip laser and the experimental results already obtained with a Tm, Ho:YLiF↓(4) crystal. By taking into account the match of the pump beam to the self-induced eigenmode of the cavity, we find good agreement between theory and experiment when the pump beam size is properly adjusted relative to the absorbed pump power and the crystal characteristics. # 1999 Optical Society of America OCIS codes: 140.0140, 140.5680.
