    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 degrees C to 98 degrees 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.
