We have investigated second harmonic generation (SHG) and sum-frequency mixing (SFG) in deuterated potassium pentaborate using N/sub 2/ laser pumped dye lasers. The crystal 90/sup 0/ second harmonic generates at 2161.5 A with a power conversion efficiency of 5% at an input power of 15 kW. Tunable phase-matched VUV SFG is observed from 2161.5 to 1962.4 A. Transmission and birefringence measurements indicate that the crystal can phase match with high conversion efficiencies to below 1700 A
