摘要： An apparatus for frequency comb generation comprises a component of second order nonlinearity, where the component is configured to interact with a laser beam or derivatives of the laser beam and thereby generate frequencies for the frequency comb. The apparatus comprises advantageously an optical manipulator, which both comprises the component but additionally is configured to introduce the beam or its derivatives in a repetitive or resonating manner to the component. The component is e.g. a monolithic or other solid optical resonator or microresonator comprising optical crystal and having said second order nonlinearity.

摘要： This invention relates to the field of laser technology and more particularly concerns to the sum-frequency generation method, where laser pulses are combined by adding their optical frequencies in a second-order nonlinear medium (3). In order to increase energy of generated sum-frequency pulses or to generate shorter sum-frequency pulses than initial light pulses, the initial light pulses are directed to the input side of the second-order nonlinear medium (3) in pairs or one by one. A first light pulse (1) of a pair or light pulses (1,1') passes through the nonlinear medium (3) without taking part in a nonlinear interaction and then it is returned via a delay line comprising mirrors (5,5') to the input side of the same second-order nonlinear medium (3). There, the first light pulse (1) overlaps in space and time with a second light pulse (1')of the pair of light pulses. In the nonlinear medium (3) the non-collinear sum-frequency between the two light pulses (1,1') is generated. The delay line may comprise a half-wave plate for rotating the polarisation of the first light pulse by 90°, i.e. type II phase-matching may be used. Instead of a pair of light pulses a sequence of identical laser pulses may be used. In this case, by properly setting the delay time, a pulse shortening between the generated sum-frequency and the input laser light may be achieved. This scheme may be used for pulse compression of a laser pulse stretched in time in a CPA using fibre amplifiers.

摘要： Embodiments of the present invention generally relate to optical mode conversion using intermodal Cherenkov radiation. More specifically, embodiments of the present invention relate to optical mode conversion utilizing intermodal four-wave mixing to convert light between modes for complex applications, whereby one of the four waves is generated from Cherenkov radiation. In one embodiment of the present invention, a fiber comprises an input end for receiving light in a first mode at a first wavelength, and an output end for outputting light in a desired second mode at a desired second wavelength; wherein the desired second mode is controlled deforming the fiber, such as by bending, during an intermodal Cherenkov radiation process.
