WAVELENGTH DISPERSION STRESS GENERATING DEVICE AND WAVELENGTH DISPERSION STRESS GENERATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a compact and inexpensive wavelength dispersion stress generating device which can generate an extremely large wavelength dispersion stress, and to provide a dispersion stress generating method.;SOLUTION: The wavelength dispersion stress generating device includes: a diffraction grating 20 for diffracting parallel light L₁; a parallel light reflector 40 for reflecting diffracted light L₂ to the diffraction grating 20; a multiple reflector 10-1 for multiply reflecting double diffracted light L₄ which has been generated by diffracting reflected light L₃ in the diffraction grating 20; and a multiple reflected light reflector 30 for making multiple reflected light L₅ emitted from an emitting window 14 of the multiple reflector 10-1 parallel to the parallel light L₁, and making the multiple reflected light L₅ incident on a grating surface of the diffraction grating 20.;COPYRIGHT: (C)2012,JPO&INPIT
