The recent Optics Letters article entitled “Flexible chirp-free probe pulse amplification for kHz fs/ps rotational CARS” by Arafat Rahman and co-authors was selected as an Editor's Pick in January 2020. See doi.org/10.1364/OL.382033.
This work will enable much improved sensitivity of femtosecond/picosecond rotational coherent anti-Stokes Raman scattering (fs/ps RCARS) thermometry and species measurements at extreme temperatures and pressures at kHz rates and with high a spatial resolution of ~90 microns. Accuracies are of the order 1-2% up to flame temperatures, as demonstrated in the figure.
