Abstract: A multiphoton-excited measuring device measuring a sample with the use of a multiphoton absorption phenomenon by optical pulses having high intensity, comprising a short pulse light source 2 emitting optical pulses; an irradiation optical system 17, 18, 19 irradiating a sample 20 with optical pulses emitted from the short pulse light source 2; a detector 24 detecting signal light generated, in association with multiphoton excitation, from the sample 20 by the irradiation with optical pulses; and an optical pulse compression means 4, 13 compressing a pulse width, with the use of intensity-dependent nonlinear effects of the optical fiber 4, so that a pulse width of optical pulses with which the sample 20 is to be irradiated is shorten to equal to or narrower than that of optical pulses emitted from the short pulse light source 2 and so that a spectral width of optical pulses with which the sample 20 is to be irradiated is wider than that of optical pulses emitted from the short pulse light source 2, which makes it possible to stably irradiate, with the use of easy-to-use short pulse light source, a sample with optical pulses having higher peak intensity and a shorter temporal width and measure the sample easily with high accuracy without requiring sophisticated laser techniques and skills.

Abstract: The optical fiber delivery system for delivering optical short pulses includes: a chirped pulse source (10) for emitting an up-chirped optical short pulse having high peak power; optical waveguide unit (20) for delivering the optical short pulse emitted from the chirped pulse source (10); negative group-velocity dispersion generation unit (30) for providing negative group-velocity dispersion to the optical short pulse exited from the optical waveguide unit (20); and an optical fiber (40) for delivering the optical short pulse exited from the negative group-velocity dispersion generation unit (30), along a desired distance, in which the optical short pulse emitted from the chirped pulse source (10) is adapted to be exited, from the optical fiber (40), as a down-chirped optical short pulse that is substantially free of waveform distortion resulting from higher-order dispersion.
