摘要：

A white light continuum was generated by focusing the terawatt 800 nm femtosecond laser pulse in Kr gas The white light spectrum spanned in a broad wavelength range from 300 to more than 2200 nm The white light continuum was used for the first time to perform direct absorption spectroscopy of CO2 at around 2000 nm in a laboratory absorption cell The present system can be used for measuring the CO2 concentrations with an accuracy of 1-2 ppm (ca 0 5%) in atmosphere for around 5 5 km propagation lengths through the air (C) 2010 The Japan Society of Applied Physics
