Experimental investigations and rate equations of quasi-continuous-wave laser operation of titanium-doped sapphire

Quasi-continuous wave titanium-doped sapphire laser pumped by frequency doubled YAG laser was investigated. The maximum average output power is 2.7 W with 11.2 W pump power, and the tuning range is 750 to 870 nm by using one set of cavity mirrors. The rate equations of this type of laser were also developed. Theoretical predictions are confirmed by experimental measurements.
