Abstract

Femtosecond optical parametric oscillator (OPO) pumped by second harmonic of Yb: KGW solid state oscillator was investigated. Comparison between LBO and BBO crystals was carried out. The phase mismatch induces cascaded nonlinearity which acts as effective nonlinear refractive index. Negative group delay dispersion (GDD) of the resonator and effective nonlinear refractive index allows linear phase and nonlinear phase compensation leading to soliton like pulse formation. Z-scan experiment was used to determine nonlinear refractive indices under conditions identical to those in the oscillator cavity. Surprisingly, the signs of nonlinear refraction as measured by Z-scan and indirectly observed in optical parametric oscillator were opposite.
