摘要： The present invention relates in general to coupling of light from one or more input waveguides to an output waveguide or output section of a waveguide having other physical dimensions and/or optical properties than the input waveguide or waveguides. The invention relates to an optical component in the form of a photonic crystal fibre for coupling light from one component/system with a given numerical aperture to another component/system with another numerical aperture. The invention further relates to methods of producing the optical component, and articles comprising the optical component, and to the use of the optical component. The invention further relates to an optical component comprising a bundle of input fibres that are tapered and fused together to form an input coupler e.g. for coupling light from several light sources into a single waveguide. The invention still further relates to the control of the spatial extension of a guided mode (e.g. a mode-field diameter) of an optical beam in an optical fibre. The invention relates to a tapered longitudinally extending optical waveguide having a relatively larger cross section that over a certain longitudinal distance is tapered down to a relatively smaller cross section wherein the spatial extent of the guided mode is substantially constant or expanding from the relatively larger to the relatively smaller waveguide cross section. The invention may e.g. be useful in applications such as fibre lasers or amplifiers, where light must be coupled efficiently from pump sources to a double clad fibre.

摘要： The present invention deals with optical systems for providing short laser pulses. An object of the invention is to provide an optical system providing compact and cost-effective short laser-pulses using fibers with anomalous dispersion and high non-linear thresholds. The object is achieved by a short pulse optical system for generating or processing short laser-pulses, said optical system comprises an optical fiber in the form of a photonic crystal fiber arranged to provide guidance of light in the core region due to the photonic bandgap effect (PBG), where light propagates in a hollow or solid core surrounded by a Silica cladding comprising a substantially periodic distribution of micro-structural elements, and where the refractive index of the core is lower than the effective refractive index of the cladding. The invention may be useful in applications such as laser-based micromachining, thin-film formation, laser cleaning, in medicine and biology.

摘要： A laser module produces pulsed laser energy in a wavelength range of 495-580 nm based on duration, peak power, and interval parameter information. An envelope timer controls the total duration of all micropulses based on the duration and interval parameters via a pulse-width modulated (PWM) output to a micropulse timer, which in turn outputs a PWM micropulse signal. A light emitting diode driver outputs a laser current through a diode based on the micropulse signal and a dimming signal to produce the pulsed laser energy. The integrator compares a signal corresponding to a detected power level of the laser energy to a signal corresponding to the peak power parameter and outputs the dimming signal. The resulting micropulse durations are in the range of 50 to 300 microseconds for periods of about 2 milliseconds, with a duty cycle ranging from 5 to 15%. The overall pulse parameters are duration from 10 microseconds to 1.5 seconds, with periods of any value. The pulsed laser energy is delivered by ophthalmologic laser treatment devices to an eye of a patient.
