Method of measuring fast time response using fast pulse and system of the same |
摘要 |
The measuring method of the invention eliminates the limitation of the observation time scale controlled of the optical path length, and expands the range of samples of the thermoreflectance method using a pulse laser. The method irradiates an extremely fast light pulse to a sample as a light pulse to excite the sample and a probe light pulse to the sample, and observes the temperature variation of the sample by detecting a reflected light from the sample. The method prepares for electrically controllable two pulse lasers: one for exciting the sample, another one for probing, separately. By electrically controlling the difference between the time at which the exciting light irradiates the sample and the time at which the probing light irradiates the sample, the method detects a signal that varies depending on the time difference between the pump pulse and the probe pulse.
