Measurements of Atomic Sodium in Flames by Asynchronous Optical Sampling: Theoryand Experiment

摘要

Asynchronous optical sampling (ASOPS) is a pump-probe method for the measurementof species concentrations in turbulent high-pressure flames. We show that rapid measurement of species number density can be achieved in a highly quenched environment by maintaining a constant beat frequency between the mode-locking frequencies of the pump and the probe lasers. A model for the ASOPS method based
