    Abstract: Disclosed herein is an all-fiber, easy to use, wavelength tunable, ultrafast laser based on soliton self-frequency-shifting in an Er-doped polarization-maintaining very large mode area (PM VLMA) fiber. The ultrafast laser system may include an all polarization-maintaining (PM) fiber mode-locked seed laser with a pre-amplifier; a Raman laser including a cascaded Raman resonator and an ytterbium (Yb) fiber laser cavity; an amplifier core-pumped by the Raman laser, the amplifier including an erbium (Er) doped polarization maintaining very large mode area (PM Er VLMA) optical fiber and a passive PM VLMA fiber following the PM Er VLMA, the passive PM VLMA for supporting a spectral shift to a longer wavelength.

    Abstract: The invention relates to a device for generating temporally distant light pulses, said device comprising a first light source (51) generating a first sequence (I) of light pulses at a first repetition rate, and a second light source (52) generating a second sequence (II) of light pulses at a second repetition rate. It is the object of the present invention to provide an improved device for generating temporally distant light pulses. This object is inventively achieved by providing for at least one actuator element which influences the first and/or the second repetition rate, and a control element (61) which charges the actuator element with a periodical modulation signal (62) for periodical variation of the first and/or second repetition rate. A control circuit is provided for, comprising a phase detector (57), which derives a control signal (58) from the first light pulse sequence (I) and the second light pulse sequence (II), a corrective element (59, 60) which derives a control deviation signal (63) from the control signal (58) and the modulation signal (62), a control element (64), at the input of which the control deviation signal (63) is pending, and a superposition element (66) which forms an actuator signal (67) from the modulation signal (62) and the output signal (65) of the control element (64), and which charges the actuator element with the actuator signal (67). Moreover, the invention relates to a method for generating temporally distant light pulses.

    Abstract: The invention relates to a method for the synthesis of electromagnetic radiation, wherein electromagnetic radiation having a spectrum comprising two or more spectral components is generated and phase setting of the electromagnetic radiation is performed. The invention proposes that the phase setting comprises phase shifting of the spectral components of the electromagnetic radiation, wherein the relative phase relationship of the spectral components is predeterminable. In addition, the invention relates to an apparatus for the synthesis of electromagnetic radiation, said apparatus comprising a pulsed laser (1), which generates a sequence of temporally equidistant light pulses, wherein the spectrum of the electromagnetic radiation of the pulsed laser (1) is the spectrum of an optical frequency comb, which is characterized by an offset frequency and a repetition rate. Furthermore, the apparatus has a phase setter (5), which effects phase setting of the electromagnetic radiation of the pulses laser (1). In accordance with the invention, the offset frequency of the spectral lines of the optical frequency comb is adjustable by time-proportional phase setting by means of the phase setter (5).

    Abstract: A method and system generates two synchronized trains of laser pulses at different wavelengths, wherein the two pulse trains are temporally synchronized and have a stable phase relation, and wherein the wavelength of one of the pulse trains is de-tunable. The method includes the steps of: generating a train of ultra-short seed laser pulses; splitting the train of seed laser pulses into a first pulse train and a second pulse train; and frequency-shifting the first pulse train by soliton self-frequency shift in an optically pumped waveguide having anomalous dispersion, wherein the spectrum of the frequency-shifted first pulse train is de-tunable by varying the pump power.
