摘要： PROBLEM TO BE SOLVED: To obtain a speckle removing light source that can remove speckle by using a laser beam, the wavelength of which is changed temporally.
SOLUTION: The speckle removing light source includes: a light source for output of a laser beam, the vertical mode of which is a single mode; a light frequency modulating means for changing the wavelength of a laser beam; a multimode optical fiber, which is long in its longitudinal direction and bent; and at least one or more condenser lenses for guiding a laser beam to the optical fiber. The condenser lens converts the condensing size of a laser beam into the size substantially equal to the size of the core diameter of the optical fiber, and also converts the number of aperture of the laser beam into the number substantially equal to the number of aperture that enables the transmission of the optical fiber. In the optical fiber, at least two or more modes are provided for light, light beams to the highest order mode from a basic mode, which are different from each other in transmission time amplified by the number of reflections within the optical fiber, are superposed in a space distribution at the emission end face, and a part including an end face, from which at least the light of the optical fiber is output, and the core outside diameter shape of a cross-section are approximately polygonal.
