摘要： A light source generates probe light to be radiated on a sample. An optical probe has a pin hole at its distal end and selectively supplies the probe light to the sample through the pin hole. An optical detecting unit detects light emerging from the sample and converts it to an electrical signal. The light source generates the probe light whose intensity changes in the pulse-like manner. The optical detecting unit detects the light emerging from the sample in synchronism with an increase in probe light which changes in the pulse-like manner and converts it to the electric signal. Therefore, noise which is conventionally converted to an electrical signal can be decreased even when the probe light which changes in the pulse-like manner is decreased, and measurement can be performed at a high S/N ratio even if the pin hole diameter is small. As a result, the resolution of a near field scanning optical microscope can be improved.

摘要： Input light incident into fiber end is separated by a light separator. Light traveling straight through the light separator is guided through an optical fiber to a light amplifying and deflecting section, where only components with deflection angle in a predetermined range are amplified and deflected then to be extracted. The extracted components are output as output light through an optical fiber. The other part of light separated by the light separator is received by a photo detector. The light received by the photo detector is converted into an electric signal, and the electric signal is then input into the light amplifying and deflecting section. Using the electric signal generated from the photo detector, desired wave shaping may be effected by adjusting a light amplification factor of the light amplifying and deflecting section, a change speed of deflection angle, and/or a range of deflection angle selected.

摘要： Light input means inputs exciting pulse light beams to a parametric oscillator simultaneously in a plurality of directions. The parametric oscillator including a parametric element such as a urea crystal produces parametric pulse beams having different wavelengths. The parametric pulse beams are corrected into coaxial beams by a correcting optical means which includes an optical fiber, and then group dispersion of the coaxial beams are compensated for by a group dispersion compensating means which includes opposed diffraction gratings.

摘要： An optically pumped solid laser that uses a corner cube or rectangular prism as its solid laser medium, containing end faces through which a semiconductor pumping light beam is applied to the medium. The solid laser medium contains at least one kind of coating formed on at least a part of an end face, such that the end face acts as a resonator and/or output mirror. Optical fibers may be connected to the end faces for inputting or outputting light beams. Non-linear crystals in waveguide form may be coupled to the outputting end face of the medium, specifically crystals of either SHG, THG, FHG, or parameteric; and KTP, .beta.-BaB.sub.2 O.sub.4, KNbP.sub.3, or MgO doped LiNbO.sub.3.

摘要： A cylindrical lens (4) diverges a laser beam (L1) in the Y-axis direction (i.e., within the YZ plane) but neither diverges nor converges it in the X-axis direction (i.e., within the ZX plane). An objective lens (5) converges the laser beam (L1) emitted from the cylindrical lens (4) into a point P1 in the Y-axis direction and into a point P2 in the X-axis direction. As a consequence, the cross section of the laser beam (L1) becomes elongated forms extending in the X- and Y-axis directions at the points P1, P2, respectively. Therefore, when the points P1, P2 are located on the outside and inside of the work (S), respectively, an elongated working area extending in the Y-axis direction can be formed in a portion where the point P2 is positioned within the work (S).

摘要： An object of this invention is to provide a pulsed laser beam source device which is easy to handle and is operative stably. Pumping light is irradiated to a laser medium from a light source for optical pumping. The stimulated laser medium pumps radiation of a set wavelength. This radiation is stimulated to be amplified while reciprocating between resonator mirrors. A multi layer film is inserted in an optical path of the radiation. Feeble light of the radiation from the laser medium is absorbed by the multi-layer to be weaker, and that part of the radiation having intensities above a set intensity is compressed in terms of time to be emitted outside. The emitted radiation has a very short pulse duration.

An objective lens (5) converges the laser beam (L1) emitted from the cylindrical lens (4) into a point P1 in the Y-axis direction and into a point P2 in the X-axis direction. A pair of knife edges (13) adjust the divergence angle (θ) of the laser beam (L1) incident on the objective lens (5) in the Y-axis direction. As a consequence, the cross section of the laser beam (L1) becomes an elongated form extending in the Y-axis direction at the point P2, while the maximum length in the Y-axis direction is regulated. Therefore, locating the point P2 on the front face of a work (S) can form an elongated working area extending in the Y-axis direction by a desirable length on the front face of the work (S).

摘要： An optical wavelength shifter shifts a wavelength of light over a wide range without need for using a large peak pump pulse. A nonlinear optical medium having a nonlinear refractive index is disposed interiorly of a laser resonator. A pump pulse and a light to be modulated are incident on a nonlinear optical medium to phase shift the light. With the provision of a timing delay unit, the timing at which the light to be modulated is incident on the nonlinear optical medium is delayed with respect to the timing at which the pump pulse is incident thereon.
