A center wavelength of first pulsed light (exciting pulsed light) is variable, and a pulse rate of the first pulsed light coincides with an integer multiple of a free spectral interval of an optical oscillator at a center wavelength of second pulsed light (signal pulsed light or idler pulsed light). A center wavelength of a nonlinear gain generated by a nonlinear optical medium is made approximately coincident with the center wavelength of the second pulsed light.

Light source apparatus, and information acquisition apparatus using the same

A signal generation method for generating an information signal F(b) by performing a Fourier transform on a signal f(a) includes the following steps: detecting the maximum peak intensity of the information signal F(b); calculating an amplitude, a phase, and a frequency of the signal f(a) corresponding to the maximum peak intensity; generating a signal by causing the signal f(a) corresponding to the maximum peak intensity to extend along an 'a' axis on the basis of information about the amplitude, the phase, and the frequency of the signal f(a); generating an extrapolation signal by extracting a signal in a region smaller than a1 and a signal in a region larger than a2 from the signal, where a1&#x3c;a2; generating a composite signal by combining the extrapolation signal with the signal f(a) in a range from a1 to a2; and performing a Fourier transform on the composite signal.

Method for generating information signal

A laser system includes a seed laser configured to generate a plurality of optical pulses; a controller configured to receive the plurality of the optical pulses and obtain chirped pulses, each chirped pulse having a chirping amount different from each other; an optical waveguide, having a characteristic of anomalous dispersion, configured to cause soliton self-frequency shifts while the chirped pulses propagating so that each center wavelength of a pulse which output from the optical waveguide is different from each other.

Fiber laser system

An apparatus for altering a chirp of an input light comprising one or more grating structures and one or more electro-optical blocks. In which a voltage is applied to the one or more electro-optical blocks to alter a chirp of light exiting the apparatus.

System for controlling the chirp of an optical signal

A fiber optic parametric amplifier that includes a resonating cavity. The resonating cavity includes linear fiber optic gain medium, with negative chromatic dispersion; and a nonlinear fiber optic gain medium with positive chromatic dispersion.
