Abstract

A robust, high-power amplifier design allows for generation of >1 MW, few-cycle pulses from a 100 MHz, 1550 nm Er:fiber frequency comb. With this source, we explore non-perturbative harmonic generation in the UV-visible in solids. In zinc oxide (ZnO) crystal, nearly continuous spectra spanning 200-700 nm are achieved and the dependence on the carrier-envelope-phase is observed and analyzed using carrier-envelope amplitude modulation spectroscopy (CAMS).
