A tunable, high-power optical parametric oscillator (OPO), using a urea single crystal as the nonlinear medium, is described. This OPO may be tuned from 506 to 900 nm when pumped with the 355 nm output of a frequency-tripled, Q-switched ND:YAG laser. An average power of 50 mW has been achieved, with conversion efficiencies exceeding 20 percent at 530 nm. The feasibility of increasing the average power to greater than 100 mW is demonstrated. High efficiency can be maintained while pumping with the near field of the Nd:YAG laser. The urea OPO is a compact, solid-state device that could be used for most laser applications requiring tunability between 500 and 1225 nm. The demonstrated high-peak power could provide efficient doubling or mixing into the 250-500 nm region, thus providing a convenient solid-state device for producing laser radiation from the UV to the near IR. Applications include spectroscopy, medicine, materials processing, nonlinear optics, and laser photochemistry.
