発明の名称 (英語) OPTICAL PULSE PAIR GENERATION DEVICE, LIGHT DETECTION DEVICE, AND LIGHT DETECTION METHOD NEW
発明の概要(英語) Provided is an optical pulse pair generation device that generates an optical pulse pair that includes first pulse light and second pulse light, which each have a central wavelength with a predetermined wavelength difference and which are set to be substantially identical target time waveforms, the optical pulse pair generation device including: a branching part which branches incident pulse light into two beams; a first shaping part which shapes one of the pulse light beams branched by the branching part into the target time waveform and sets the center frequency thereof so as to obtain the first pulse light; and a second shaping part which shapes the other pulse light beam branched by the branching part into the target time waveform so as to obtain the second pulse light.
従来技術、競合技術の概要(英語) BACKGROUND ART
The coherent Raman scattering microscopy, molecules present in tissue or cells of non-staining and at a high speed known as imaging techniques can image. The coherent Raman scattering microscopy, and coherent anti-Stokes Raman scattering (Coherent Anti-stokes Raman Scattering; CARS) such as the stimulated Raman scattering (Stimulated Raman Scattering; SRS) is used as the non-linear optical processes. The coherent Raman scattering microscopy, these nonlinear optical processes to interactions with light and detecting Raman scattered light generated by the acquired information of the molecular vibration is reflected on the basis of the level of the signal, the distribution of the concentration of chemical substances to the diffraction limit of light level (for example, 1μm (micrometer) or less) in the spatial resolution of the drawing device. For example see, Coherent Raman scattering microscopy, J.-X. Cheng and X. S. Xie Eds, (Taylor and Francis Books Inc., 2011)..
The conventional, coherent Raman scattering microscope have been known several methods, among others, time-resolved coherent Raman scattering microscopy, cells and tissue to reduce the background noise itself, such as small molecule drug is the signal of the molecular vibrations of a particular frequency having high contrast has been attracting attention as a method of detecting. For example, A. Volkmer, L. D. Book, and X. S. Xie, "Time-resolved coherent anti-Stokes Raman scattering microscopy: Imaging based on Raman free induction decay,"Appl. Phys. Lett. 80, 1505-1507 (2002). reference.
In recent years, as a development of the technique of time resolved coherent Raman microscope, the spectral collection to achieve high spectral resolution using the irregularities by a technique has been proposed. See for example T. Ito, Y. Obara and K. Misawa, "Single-beam phase-modulated stimulated Raman scattering microscopy with spectrally focused detection,"J. Opt. Soc. Am. B 34, 1005-1017 (2017)., P. K. Upputuri, L. Gong, and H. Wang, "Chirped time-resolved CARS microscopy with square-pulse excitation,"Opt. Express 22, 9611-9626 (2014). and. Spectrum and the light collection method, for example femtosecond pulse 2 is generated for the same one of the group delay dispersion of the given (linear chirp), the frequency of the beat of the peak in the Raman vibration corresponding to the selective excitation, or by the probe, high resolution microscopic spectroscopy technique implemented., T. Hellerer, A. M. K. Enejder and A. Zumbusch, "Spectral focusing for example: high spectral resolution spectroscopy with broad-bandwidth laser pulses,"Appl. Phys. Lett. 85, 25-27 (2004). reference.
