Measurement of ultrashort optical pulses by third-harmonic generation

Interferometric and intensity autocorrelations by third-harmonic generation for the measurement of ultrashort optical pulses are demonstrated. The third-harmonic signal is generated by tight focusing of the ultrashort pulses upon the surface of an ordinary glass slide, replacing the high-optical-quality nonlinear crystals used in conventional second-harmonic generation measurements. The method is shown to be applicable to real-time measurements.
