Two-beam femtosecond coherent anti-Stokes Raman scattering for thermometry on CO2

We show that two-beam femtosecond coherent anti-Stokes Raman scattering can be effectively used for thermometry on CO2 for temperatures between ∼100 °C and ∼600 °C at a maximum pressure of 8.5 bar. The temperature measurement is based on probing the vibrationally excited states of CO2, using a ∼7 fs pump/Stokes pulse and a narrowband (∼0.3 nm) probe pulse. The temperatures can be derived from a single spectrum, obviating the need for a delay scan or a chirped probe pulse.
