Abstract: An optical fiber is inserted into an inside portion of a hollow tube of an insert and guides light emitted from a light source. A base end section includes an optical fiber insertion part used for inserting the optical fiber. An optical fiber fixing member fixes the optical fiber at a position spaced from a distal end of the optical fiber. The optical fiber insertion part has a first portion into which the optical fiber fixing member is inserted. The first portion has at least three protrusions protruding toward the center at positions spaced from each other in a circumferential direction. A size of the optical fiber fixing member in a direction perpendicular to an insertion direction into the first portion is larger than that of an inside portion of the first portion, and the optical fiber fixing member is harder than the first portion.

Abstract: Using a laser source unit, a plurality of wavelengths are switched at a high speed without increasing a rotation speed of a birefringent-filter. A Q switch and a birefringent filter are inserted into an optical resonator including a pair of mirrors facing each other with a laser rod interposed therebetween. The birefringent-filter changes an oscillation wavelength of the optical resonator in association with rotational displacement. Driving unit reciprocatively rotates the birefringent-filter in a predetermined range including a discontinuous point of change characteristics of a transmission wavelength for the rotational displacement. An emission control unit irradiates the laser rod with excitation light from a flash lamp, and then turns on the Q switch at a timing when a rotational displacement position of the birefringent-filter is set to a position corresponding to the wavelength of the pulse laser beam to be emitted, to cause the pulse laser beam to be emitted.
