16kw and 48kw end - pump disk amplifier were designed , they condensed the pump radiation of the two diode arrays of 36 times and 27 times separately , which average radiant intensity were lower than 0 . 5kw / cm ~ 2
2.
It includes the requests of two respects : condense the pump radiation of large - scale diode arrays efficiently , thus in gain medium realize the high density of energy storage ; improve space distribution of the pump radiation , realize perfect pumping - uniformity in the gain medium
