A novel technique by adopting pump-probe detection to thermal lens spectroscopy has been proposed for investigating fast nonradiative relaxation processes. It was applied to measurements of the relaxation of Rhodamine 6G in various solutions. The results show that nonradiative relaxation processes can be observed with time resolution of sub-nanosecond.
