Abstract
We use a single cavity in which the second harmonic is resonant to fir st double and then quadruple the IR input. The cavity is powered by a 15-W cw mode-locked Nd:YLF laser. We generate intermittent 263-nm aver age powers as high as 6.7 W for eta(IR-->UV) = 45%. Absorption of 527- nm radiation in the beta-barium borate crystal degrades the performanc e during continuous operation. The highest continuous average UV power produced is 2.9 W (simultaneously; 3.6 W of 527-nm light is output).
