Mid-infrared chirped-pulse upconversion with four-wave difference frequency generation in gases

Abstract

Chirped-pulse upconversion of sub-single-cycle mid-infrared pulses with gaseous media has been realized. Single-shot detection of mid-infrared spectra from 250 to 5500 cm(-1) with 5 cm(-1) resolution was demonstrated. (C) 2013 Optical Society of America
