発明の名称 (英語) | PUMP-PROBE MEASUREMENT DEVICE |
発明の概要(英語) |
A pump-probe measurement device (1) comprises: an ultrashort optical pulse laser generating unit (2) for generating a first ultrashort optical pulse train serving as a pump beam (3a) and second and third ultrashort optical pulse trains (3b, 3c) serving as probe beams and an optical shutter unit (6) into which the second and third ultrashort optical pulse trains (3b, 3c) are made incident. The pump-probe measurement device (1) further comprises a detection unit (20) including: an irradiation optical system (8) for irradiating a sample (7) with the pump beam (3a), the first probe beam (3b), and the second probe beam (3c) a sensor (11) for detecting the probe beams from the sample (7) and a phase-sensitive detection means (12) connected to the sensor (11). An optical shutter control unit (10) periodically modulates the delay times of the first probe beam (3b) and the second probe beam (3c) to the pump beam (3a). These modulated first and the second probe beams (3a, 3b) are alternately applied to the sample (7), and probe signals from the sample (7) are detected by the phase-sensitive detection means (12) in synchronization with periodical modulation signals of the delay times. |
