Pump-tuning ktp optical parametric oscillator with continuous output wavelength pumped by a pulsed tunable ti:sapphire laser

摘要

We report on the implementation of a KTP optical parametric oscillator pumped by a pulsed tunable Ti:sapphire laser. Two major improvements were achieved, including the connection of the signal and idler tuning ranges and the high-output conversion efficiency trough the signal and idler tuning ranges. Both in the signal and idler, the continuous output wavelength from 1.261 to 2.532μm was obtained by varying the pump wavelength from 0.7 to 0.98μm. The maximum output pulse energy was 27.2mJ and the maxium conversion efficiency was 35.7/100 at 1.311μm (signal).
