Experimental Setup build for the measurement of Radiative lifetimes, branching fractions, and absolute transition probabilities in atomic samarium using Laser Induced FLuorescence, at Laser & Plasma Division, BARC, Mumbai .
The Laser Induced Fluorescence Setup displayed above uses a Tunable dye lasers (Quantel TDL90) pumped by a Q-switched Nd:YAG laser (Quantel YG980), along with a gated ICCD Camera (4 Quik E,Stanford Computer, Inc) and PMT which are coupled to a monochromator.

Left Image: Experimental time-resolved single-color LIF decay signal with an exponential fit. The lifetime for this level (18,225.13 cm-1) is measured to be 143±10 ns.
Right Image: Experimental time-resolved two-color LIF decay signal with an exponential fit. The lifetime for this level (34,814.4 cm-1) is measured to be 127±13 ns.

Spectrally resolved LIF showing three different decay channels form the excited level at 18,475.28 cm-1. In the inset, the solid line represents laser-induced excitation and the dotted lines represent the observed fluorescence.
