Abstract

Due to their large spectral bandwidth sub ∼20 fs pulses are a versatile tool in spectroscopy, but for applications in gases comparably high pulse energies are required. These pulses are easily subject to distortions of the spectral shape, phase and shot-to-shot stability. We investigate the excitation efficiency for two-beam ultrabroadband fs/ps coherent anti-Stokes Raman scattering (CARS) using a shot-to-shot stable BBO-based optical parametric chirped pulse amplifier (OPCPA). Up to 10 bar, quantitative concentration measurements with and without consideration of the excitation efficiency measured in argon are investigated for ternary gas mixtures with Raman shifts up to ∼3000 cm−1
