発明の名称 (英語) Pump probe measuring apparatus
発明の概要(英語) A pump probe measuring apparatus (1) includes an ultrashort light pulse laser generator (2) for generating a first ultrashort light pulse row as pump light (3a) as well as second and third ultrashort light pulse rows (3b), (3c) as probe light, and a light shutter (6) to which the second and third ultrashort light pulse rows (3b), (3c) are incident, and further includes a detector (20) having an irradiation optical system (8) for irradiating the pump light (3a), the first probe light (3b) and the second probe light (3c) to a sample (7), a sensor (11) detecting a probe signal from the sample (7) and a phase-sensitive detecting means (12) connected to the sensor (11), wherein delay times of the first probe light (3b) and the second probe light (3c) with respect to the pump light (3a) are periodically modulated by a light shutter controller (10), the modulated first probe light (3b) and second probe light (3c) are alternatively irradiated to the sample (7), and the probe signal from the sample (7) is detected by the phase-sensitive detecting means (12) in synchronization with the periodically modulated signal of the delay time.
