A technique in which a sample is first excited by a strong pulse (the 'pump' pulse) of light from a laser. This first pulse starts a chemical reaction or leads to an increased population of energy levels other than the ground state within the sample. The absorption of light by the sample is recorded within a short time intervals (by a 'test' or 'probe' pulse) to monitor relaxation or reaction processes initiated by the pump pulse.
