To improve operation parameters (S/N ratio, dynamics range, time resolution, etc.) of picosecond streak tubes, the traditional P20/P43 phosphor screens can be replaced by the others (P46/P47) having much faster decay time of the luminescence output.

Coherent anti-Stokes Raman scattering (CARS) spectroscopy has been used to investigate cryogenic liquid oxygen/gaseous methane (LOX/CH4) flames on a medium-size test facility at a pressure of 0.24 MPa and mass flow of 0.025 kg/s. Single-shot, broadba

A high-resolution (∼0.1 cm−1) spectroscopic method based on the application of a Fabry–Perot interferometer to the spectral analysis of the coherent anti-Stokes Raman scattering (CARS) signal from an individual Raman transition was used to obta

In the present paper a high-resolution spectroscopic method, that allows obtaining single shot spectra of Raman-active molecular transitions in non-stationary media with a resolution of ~0.1 cm-1, was developed. The method is based on application of

Hydrogen Q-branch rotational component line-broadening coefficients for hydrogen–water collisions were determined at 2700 K. For linewidth measurements CARS spectroscopy with a Fabry–Perot interferometer and a multichannel detector was applied. I

In this work, we present the results of two-wavelength (2λ)-CARS thermometry of hydrogen at temperatures from 300–1200 K. The choice of the pair of spectral lines for the 2λ-CARS thermometer with respect to optimal temperature sensitivity within
