Significant enhancement of third- and fifth-harmonic generation in air via two-color, time-resolved methods

Darshana L. Weerawarne; Rostislav I. Grynko; Henry J. Meyer; Bonggu Shim

We report two orders of magnitude enhancement of third- and fifth-harmonic generation in air via time-resolved methods using two-color, femtosecond beams. We attribute the significant enhancement to cross-phase modulation and/or plasma assisted phase matching effects.
