Abstract
Beta-barium borate (BBO) has recently emerged as new nonlinear material for frequency conversion of laser lights. Its paticularly wide range for frequency conversion, high damage threshold, wide temperature acceptance width and good chemical stabilities have led to a large number of applications 1-4. However, until now a few reports have been concerned with intracavity frequency conversion experiments using BBO 5-6. We have developed intracavity frequency mixing system, including frequency doubling (SHG), using an argon laser of all lines output power of 2W. In this initial demonstration, we obtained 36 lines of deep ultra-violet wavelengths ranging from 228.9nm to 257.2nm . The maximum output of 33mW was obtained at 250.4 nm by the sum frequency generation of 488.0nm and 514.5nm radiations.
