A method of measuring fluorophore excited state lifetimes comprising initiating an excitation laser pulse at a dye to excite dye molecules of the dye from a ground state to an excited state and initiating a probing pulse at the dye molecules thereby generating a first set of photoacoustic waves at a first time delay resulting in a first intensity point. The process can be repeated, optionally introducing a second excitation laser pulse, to generate a second set of photoacoustic waves at a second time delay resulting in a second intensity point. The data can be analyzed to determine a slope between the first intensity point and the second intensity point.
