摘要： Young's interferometer consisting of a single slit and a double slit member, and an analyzer are arranged along the axis of light to be measured. Parallel slits of the double slit member are provided with respective polarizers whose paralyzing directions are at .+-.45.degree. to the longitudinal direction of the parallel slits. The polarizing direction of the analyzer is set in parallel with the parallel slits. The incident light passes through Young's interferometer and the analyzer to form an interference fringe, which is detected by an image detector unit. An image analyzer unit produces an intensity profile of the interference fringe and determines the polarization state of the incident light, for instance, by comparing the produced intensity profile with conceivable profiles stored in advance.

摘要： A system for measuring timing relationship between two signals for accurately measuring a timing relationship between signals includes an electro-optic measuring unit and a waveform storage and processing unit. The electro-optic measuring unit samples electrical signals from a device under measurement via a strobe light so as to measure the signal waveform. The electro-optic unit uses a laser diode as a light source. The waveform storage and processing unit stores the electrical signal waveforms measured by the electro-optic measuring unit in digital form. The waveform storage and processing unit also calculates a correlation between two stored electrical signal waveforms via a correlation calculation unit, and also detects a peak of the correlation to detect a timing relationship between the signals.

摘要： A change in voltage can be sensitively detected at a local part of a measured object. A set of laser medium and E-O probe are disposed between a pair of mirrors, a first one and a second one, forming a laser resonator. A linearly polarized light is emitted from the laser medium. The polarized light enters the E-O probe, and returns after being reflected by the second mirror. When a voltage is given to the E-O probe from the measured object, depending on the voltage, a refractive index of the E-O probe is changed, the light emitted from the E-O probe is ovally polarized, and a resonance status of the laser resonator then varies. Therefore, the light intensity emitted through the partially penetrating first mirror to the outside of the laser resonator corresponds to the voltage at the measured object in the proximity of the E-O probe. Consequently, a voltage distribution on the measured object such as IC with fine structures can be two-dimensionally detected.

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.

摘要： The optical apparatus includes first and second deflection members, a mask, a pumping light source, and a controller. The first and second deflection members are formed of nonlinear optical material whose refractive index is changed upon light radiation. The mask is arranged on an optical path extending from a front side of the first deflection member to a rear side of a second deflection member. The mask has a predetermined transmission pattern. The pumping light source radiates first and second beams on predetermined regions of the first and second deflection members. This changes the refractive indices of the predetermined regions to bend the optical path. The controller variably controls the intensity of the first and second beams.

摘要： A semiconductor light amplifier is driven by a drive device, and selectively amplifies one of a TM mode component and a TE mode component of input light. For example, TE mode light is selectively amplified by making thickness of the active layer of the semiconductor light amplifier not more than 0.05 .mu.m, or by tilting at least one of the entrance and exit faces of the semiconductor light amplifier by 10 to 16 degrees. An another type of light amplifying polarizer, input signal light and excitation light are combined by a half mirror or an optical coupler, and combined light is input to a rare-earth-element doped, polarization maintaining optical fiber.
