Dual-Pump Coherent Anti-Stokes Raman Scattering for Simultaneous Pressure/Temperature Measurement

A new dual-pump coherent anti-Stokes Raman scattering technique for the simultaneous measurement of pressure and temperature is discussed. For these measurements the wavelengths of the two pump lasers the Stokes laser are selected so that the vibrational and pure rotational spectra of nitrogen are s...

Zusammenfassung:	A new dual-pump coherent anti-Stokes Raman scattering technique for the simultaneous measurement of pressure and temperature is discussed. For these measurements the wavelengths of the two pump lasers the Stokes laser are selected so that the vibrational and pure rotational spectra of nitrogen are simultaneously acquired.
