Abstract

Efficient operation of cw mode-locked singly resonant optical parametric oscillators (OPO’s) of critically phase-matched KTiOPO4 is demonstrated. The OPO’s are synchronously pumped by the 1053-nm fundamental or the 527-nm second harmonic of a 76-MHz-repetition rate mode-locked Nd:YLF laser with pump-pulse lengths of 40 and 30 ps, respectively. Tuning of the OPO’s is accomplished by changing the phase-matching angle. The 527-nm-pumped system has been investigated in the tuning range from 1.01 to 1.1 μm. At a pump power of 1.3 W this OPO generated 14-ps-long pulses with a total average power of 580 mW, yielding an efficiency of 44%. The 1053-nm-pumped OPO produced powerful infrared radiation in the ranges from 1.55 to 1.56 μm (signal wave) and from 3.22 to 3.28 μm (idler wave). For 14 W of pump power the average output power of the 12-ps-long pulses exceeded 2.0 W for the signal wave and 0.8 W for the idler wave. The total output power corresponds to an efficiency of 21%.

Schematic diagram of the OPO resonator that is used for the 527-nm-pumped xy-KTP OPO. For the xz-KTP OPO pumped by the 1053-nm laser radiation the polarizing beam splitter is omitted. In this case the idler wave is extracted through the spherical dichroic mirror. The indicated second-harmonic generation (SHG) is required only for the xy-KTP OPO. LBO, lithium trioborate; FPE, Fabry–Perot étalon.
