摘要： PROBLEM TO BE SOLVED: To provide a pulse laser generating apparatus which has a low pedestal or has a pedestal suppressed. SOLUTION: A pulse laser generating apparatus includes a laser configured to generate a pulse of a laser beam, a fiber amplifier, and a pulse compressor. The fiber amplifier includes a rare-earth doped fiber that exhibits normal dispersion at a wavelength of the laser beam generated from the laser. The pulse laser generating apparatus further includes a unit configured to give a loss to energy portions in a wavelength region corresponding to a zero-dispersion wavelength of the rare-earth doped fiber or a wavelength region longer than the zero-dispersion wavelength within a wavelength spectrum of the laser beam having been chirped in the fiber amplifier.

摘要： PROBLEM TO BE SOLVED: To provide a pulse compressor in which the generation of pedestal components accompanied by pulse compression is reduced or suppressed.
SOLUTION: The optical pulse compressor includes a chirp part 1 including a normal dispersion fiber which provides a positive chirp to an incident pulse, and a dispersion compensation part 2 including an anomalous dispersion fiber. A nonlinear coefficient and an absolute value of a second-order group velocity dispersion of the anomalous dispersion fiber which constitute the dispersion compensation part 2 is set such that a soliton order becomes one or more. Therein, a fiber length of anomalous dispersion fiber is equal to or smaller than the length required for optical soliton formation.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for measuring a terahertz wave, capable of acquiring spectral information (e.g., amplitude information of each frequency component, intensity information on each frequency (wavelength)) from a time waveform without Fourier-transforming the time waveform. SOLUTION: The apparatus includes a dispersing section 103 for chirping the terahertz wave 104 generated from a generating section 101. Waveform information on the terahertz wave chirped by the dispersing section 103, is detected by a detecting section 102. Accordingly, information about a frequency included in the waveform information can be obtained from the waveform information. COPYRIGHT: (C)2009,JPO&INPIT
