Experime t al setup a d t he properties of its i put-output power were i troduced. From the poi t of gai distributio , the co figuratio of the LD-pumped laser was optimized. The maximum output power of the NdBYAG laser was about 575 W. The output pow er was i creased li early w ith the pump power at the slope efficie cy of 47% above the threshold. The optical-to-optical efficie cy of 26. 1% w as obtai ed. T hrough H e- Ne laser pro
