• The temperature measurement accuracy of N_2 Q-branch CARS (Coherent Anti-Stokes Raman Spectroscopy) below 1000K has been improved by improving the spectral resolution of the detection system. The total spectral resolution was improved from 1. 3cm^<-1> to 0. 6cm^<-1> by dispersion magnification (×3. 6) , which was effected by adding a magnifier between a monochromator and an intensified photodiode array detector. The accuracy of temperature measurement in the temperature range of 300-800K for pressures of 0. 1-3. 0MPa has been greatly improved from ±100K, in the case without the magnifier, to ±40K. The method reported in this paper has a potential advantage for practical use because of its convenience.
