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.

摘要： Tunable monolithic cavity-based frequency converter pumped by a single-frequency laser where cavity resonance(s) are achieved by independently changing the temperatures, T C , T R /T L of different sections of the crystal, including the periodically poled section and one or more adjacent, non-poled regions. Having independent control of the phase matching temperature and the cavity resonance for a down-converted beam increases the efficiency.

摘要： This invention relates to the field or laser technology and is designed to multiplex in time laser pulses from several initial laser sources, generating a sequence of sum-frequency pulses in the second-order nonlinear medium. The light pulse generation method comprises direction of light pulses generated by separate laser sources to the optical means, where light pulses generated by separate laser sources are composed in one sequence of light pulses, and said light pulses propagate in the same trajectory, composing a multiplexed in time beam of light pulses. In order to increase energy and average power of the sequences of multiplexed in time light pulses of the summed optical frequency, said optical means is at least one second-order nonlinear medium, light pulses generated by separate laser sources are directed to it at predetermined time moments in directions that satisfies the phase-matching conditions, the light pulses of the summed optical frequency are generated at different time moments in second-order nonlinear medium, and they do not overlap and compose multiplexed in time beam of light pulses.
