【Abstract】 The femtosecond time resolved fluorescence depletion method has been introduced.In this method two beams of femtosecond laser was used.One excited the sample molecular to emit fluorescence.Then after specified time delay the second laser beam was introduced to deplete the fluorescence through the stimulate emission process.This method has been applied to LDS751 molecules in solution and its time resolved fluorescence spectrum has been obtained.更多还原
