Nonlinear Optics with Phase-Controlled Pulses in the Sub-Two-Cycle Regime
Journal Article
·
· Physical Review Letters
Nonlinear optical effects due to the phase between carrier and envelope are observed with 5fs pulses from a Kerr-lens mode-locked Ti:sapphire laser. These sub-two-cycle pulses with octave spanning spectra are the shortest pulses ever generated directly from a laser oscillator. Detection of the carrier-envelope phase slip is made possible by simply focusing the short pulses directly from the oscillator into a BBO crystal. As a further example of nonlinear optics with such short pulses, the interference between second- and third-harmonic components is also demonstrated.
