摘要： A fundamental wave (15) is caused to enter a Cerenkov-radiation type optical wavelength converter device (10) which is formed of a single-crystal organic nonlinear optical material (11) of an orthorhombic system of mm2 point group disposed in a cladding (12) as a waveguide and a wavelength-converted wave such as a second harmonic whose wavelength is within the range of 430 to 500nm is extracted. The wavelength of said fundamental wave (15) is selected so that the wavelength of the wavelength-converted wave (15') becomes longer than the absorption edge of the organic nonlinear optical material by at least 30nm. The fundamental wave (15) is linearly polarized in the direction of the x-optic-axis or the y-optic-axis of the crystal of the organic nonlinear optical material and then caused to enter the optical wavelength converter device (10), and a wavelengthconverted wave (15') which is linearly polarized in the z-optic-axis of the crystal is extracted.

摘要： A bulk crystal type optical wavelength converter device (110) is made of a monocrystalline nonlinear optical material (3.5-dimethyl-1-(4-nitrophenyl)pyrazole, referred to as PRA). A linearly polarized fundamental having a wavelength ranging from 900 to 4000 nm is applied to the bulk monocrystalline nonlinear optical material to achieve angular phase matching of the type I for obtaining a second harmonic of the fundamental. An optical wavelength converter module comprises a fiber type optical wavelength converter device (110) and a light source device (120). The optical wavelength converter device (110) includes a core (111) made of a monocrystal of the PRA which has has a crystal orientation such that the c-axis thereof extends substantially along the axis of the core (111). The light source device (120) applies, to the optical wavelength converter device (110), a fundamental which is linearly polarized in the direction of the a-axis or b-axis of the crystal which is normal to the c-axis.

摘要： An arrangement for generating light at a second harmonic of an input light at a fundamental frequency/wavelength. Light at the fundamental frequency/wavelength is generated by a laser (1) and impinges upon an input end of an optical fiber (4). The optical fiber has a non-linear optical characteristic and generates a second harmonic of the input light. The second harmonic which exits the fiber (4) has an axisymmetrical and conical equiphase wave surface. A collimator lens (5) collimates the second harmonic and parallel light rays are produced on the output side of the lens.

摘要： An optical waveguide (11) includes a region (22) which, after electrical poling of a guiding region (16), maintains an internal electric field induced by the poling potential. The internal electric field may arise from charge separation between regions (18, 20) induced by an adjacent poling electrode (12A), and region (22) acts to inhibit decay of the space charge and to increase the lifetime of the induced electro-optic effect. The waveguide may comprise a twin hole optical fiber (11) with internal electrodes (12A, 14A), where the region (22) comprises a borosilicate layer concentrically disposed about one of the electrodes.

摘要： A compact variable-wavelength short pulse light generating device and method for generating an ideal soliton pulse of femtoseconds whose wavelength can be varied without adjusting the optical system. The device includes a short pulse light source (1), an optical characteristic adjustor (2) for adjusting the optical characteristic of the light generated by the short pulse light source (1), and an optical fiber (3) for receiving an incident pulse from the adjustor (2) and linearly varying the wavelength of the output pulse. A short pulse light is made to enter the optical fiber, and a soliton pulse is generated by using the nonlinear effect of the optical fiber, thereby shifting the wavelength of the soliton pulse linearly with respect to the strength of the incident light by using the nonlinear effect.

摘要： The invention relates to a device for the production of tuneable light impulses in a visible spectral range, comprising a laser system (LS) which emits femtosecond light impulses in the infrared spectral range, and an optical frequency converter (FC) for converting the wave lengths of the light impulses into the visible spectral range. According to the invention, the wave length of the light impulse emitted by the laser system can be tuned in order to provide said type of device which can be used as a light source for time-resolved fluorescence spectroscopy. Said device also comprises an optical stretcher which enables the duration of the impulse of the frequency converted light impulse to be increased to at least 1 ps.

摘要： A method of thermally poling a silica based waveguide (12) comprises exposing a region of the waveguide (12) to an electric field (for example, via capillary electrodes (22, 24) inserted into holes in the waveguide); directing a laser beam (18) into the region exposed to the electric field to effect localised heating of the region via direct absorption; and scanning the laser beam (18) over the region at a rate selected to avoid heating of the region above the glass transition temperature. Reversing the electric field while scanning the laser beam (18) allows the formation of periodic poled gratings. The waveguide (12) can comprise an optical fibre.
