    Line strengths and nitrogen (N-2)-broadening coefficients for six nitrous oxide transitions were measured using a continuous-wave quantum cascade laser (cw-QCL) operating near 4.56 mu m. The temperature dependence of the exponent n for the N-2-broadening coefficients was determined over the range 298-800 K using a sapphire-sealed optical cell. Spectral parameters were determined by fitting absorption spectra with multi-peak Voigt profiles. The line strengths for the six transitions are 0-3% larger than those in the HITRAN 2012 database, while the N-2-broadening coefficients at the reference temperature are 2-5% smaller than the HITRAN 2012 values.
