High average power UV generation at 0.266 mu m in BeSO/sub 4/.4H/sub 2/O

A report on the efficient generation of highly stable 1.7-W average power UV pulses at 0.266 mu m in BeSO/sub 4/.4H/sub 2/O is presented. BeSO/sub 4/.4H/sub 2/O has been found to be a superior material for high peak-power and high average-power UV generation at 0.266 mu m. A Gaussian-like beam having an average power of 1.7 W was generated without damage to the crystal at room temperature.<
