Abstract

The construction of a distributed-feedback (DFB) dye laser and its use as an excitation/ionization source for the lifetime measurement of chlorobenzenes based on the pump-probe method were discussed. The approach provided data on a collision-free lifetime at a resonance line. The pulse width and the linewidth of the laser used were 160 ps and 9.64 pm, respectively. Results showed that the pulsewidth was reduced to 80 ps using a quenching technique and to <20 ps using a picosecond pump source.
