Abstract :
Z-scan measurements of the ground and excited state absorption cross sections of Cr4+-doped yttrium aluminum garnet are reported. These quantities are found to depend on crystal preparation but are independent of temperature from -60°C to 98°C. Their ratio is shown to weakly determine the energy output of a passively Q-switched Nd:glass laser using this material as the saturable absorber
