Abstract
This paper represents the line parameter measuring results base on pulsed DFB quantum cascade laser with tunable in the spectral range of 1248-1257 cm-1. The transition is in the υ4 band and P (8) branch which is lying in the line position of 1253.46436 cm-1based on HITRAN simulation. The calculated line intensity is 1.85×1020 cm-1/cm-2molecule and the pressure broadening parameters in N2and Ar are 0.061± 0.003 cm-1atm-1and 0.086 ± 0.007 cm-1atm-1respectively.
