Abstract: An irradiation probe is, for example, an irradiation probe in which a plurality of optical fibers are bundled together, each of the optical fibers having, as at least a partial section in a longitudinal direction, a leakage section that outputs leakage light radially outward. Each of the optical fibers has directivity in which intensity of leakage light in a specific radial direction is higher than intensity of leakage light in another radial direction in a cross section intersecting an axial direction of the leakage section. The optical fibers are disposed apart from a central axis of the irradiation probe in radial directions different from each other, and the optical fibers are bundled together in a posture in which leakage light to the specific radial direction from the leakage section is directed radially outward of the irradiation probe.

Abstract: A method and a system for photoacoustic inspection of a part are provided herein. The method may include the following steps: photo-acoustically exciting a predetermined position in a predetermined region on a part by pulsed laser illumination, to yield ultrasonic excitation of the part; coherently illuminating a predetermined location in the predetermined region on the part; detecting an illumination scattered from the predetermined location; determining, based on the scattered illumination, a plurality of sequence of two or more temporally-sequential de-focused speckle pattern images, wherein each of the sequences corresponds to one of the predetermined illuminated locations; and determining a set of translations, each determined based on the sequences, wherein each translation in the set is determined based on two temporally-sequential speckle patterns images in the respective sequence.

Abstract: On-line detection of mesophase particles employs a laser diode light source to illuminate a target area with a pulsed laser linearly or circularly polarized probe beam. Analysis of images determines extent of presence the birefringent mesophase particles, which are precursors to coking in catalytic hydrocracking processes. The inherently polarized low-coherence, unfocused but sufficiently collimated, pulsed laser beam yield sharp imaging with high depth of field of very small mesophase particles that are present in a moving, dark reactor liquid environment.

Abstract: A method of generating laser pulses (1) includes: creating a circulating light field in resonator device (11) having resonator length L and an intra-cavity dispersion and configured for supporting light field resonator modes, and generating a pulse train of laser pulses (1) by a mode-locking mechanism. Laser pulses (1) are generated with a repetition frequency and provide a frequency comb with carrier frequency ωo and comb modes in frequency space. The intra-cavity dispersion is selected such that round trip phases ϕ have a dependency on frequency ω according to φ ( ω ) = π m ( 1 + 4 ω - ω 0 m ω r - 1 ) + L c ω 0 wherein m is an integer providing effective repetition rate (mωr) in combination with mode spacing ωr at optical carrier frequency (ωo), and the mode-locking mechanism provides a coupling of the resonator modes whereby frequency difference (Δn=ωn+1−ωn) between neighboring mode frequencies (ωn, ωn+1) is a linear function of mode frequency number n. Furthermore, a spectroscopy method for investigating a sample, a laser pulse source apparatus and a spectroscopy apparatus are described.

Abstract: A spheroidal mirror reflectivity measuring apparatus for extreme ultraviolet light may include an extreme ultraviolet light source, an optical system, and a first photosensor. The extreme ultraviolet light source may be configured to output extreme ultraviolet light to a spheroidal mirror that includes a spheroidal reflection surface. The optical system may be configured to allow the extreme ultraviolet light to travel to the spheroidal reflection surface via a first focal position of the spheroidal mirror. The first photosensor may be provided at a second focal position of the spheroidal mirror, and may be configured to detect the extreme ultraviolet light that has passed through the first focal position and then has been reflected by the spheroidal reflection surface.

Abstract: Spectral data such as a CARS spectrum of a sample is acquired at high speed by reducing the amount of data. During scan by emission light focused and emitted onto the sample, the exposed state of a detection unit of a spectroscope that divides light generated from the sample is continued, thereby acquiring spectral data obtained by summing spectra generated at a plurality of positions in the sample.
