Abstract

This paper presents hybrid femtosecond/picosecond CARS measurements of the vibrational temperature of a femtosecond laser-induced plasma filament with and without the addition of an overlapping nanosecond laser. The femtosecond filament is produced in air at atmospheric pressure. Measurements obtained from 2 to 20 μs after the generation of the femtosecond filament show that the femtosecond filament produces a significant vibrational heating of the gas up to 2500 K. The nanosecond pulse when applied 3.6 ns after the femtosecond pulse is responsible for an additional vibrational heating of approximately 300 K.
