Experimental setup for the gas-phase detection of PbCl₂. The transmission of the probe laser (405 nm) through a sample volume (SV) was monitored by a photodiode (DET) for collinear photofragmentation and atomic absorption spectroscopy (CPFAAS) signal upon double photofragmentation process of 355 nm and 266 nm laser pulses. Pulse energies were monitored by energy meters (EM) at the input and output. Beam splitters (BS) and dichroic mirrors (DM) were used to split, direct, and co-align the beams. An oscilloscope (OSC) was used for recording the signal for further analysis.
