摘要

The typical laser characteristics of a laser diode pumped solid-state laser with a Z-type resonator structure are analyzed by the transform circle approach. Laser waists change with the thermal focus length of the lasing medium so that the output power becomes unstable. In particular, there is a. very unstable operation region when the pump power is of medium magnitude. A method is put forward to avoid this situation.
