Abstract
This paper describes an Nd:glass slab amplifiers with 24cm-square aperture, and tested it at different charge voltage. Under the condition of charge voltage 22kV and pumping energy density of 14.62J/cm 3, obtain small signal gain coefficient of 4.9%cm -1 and energy storage efficiency of 2.43%.
