A femtosecond single-crystal sum-frequency generating optical parametric oscillators (OPO) based on a Ti:sapphire laser pumped KTiOPO4 crystal was used. presented. The crystal was phase matched for a specific signal wavelength corresponding to the operational wavelength of the laser. The crystal was also phase-matched for the sum-frequency generations (SFG) of the pump and the signal beams yielded a blue output beam. The conversion efficiency of the OPOs increased by compensating the group velocity mismatch.EnglishLight polarizationMathematical modelsOptical frequency conversionOptical pumpingOptical rotationRunge Kutta methodsSolid state lasersNon-critical phase matching (NCPM)Sum-frequency generation (SFG)Optical parametric oscillatorsConference Paper10.1109/NLO.1998.710262
