Abstract: A pulse application method includes: setting a wavelength of light within a range in which a temperature rise width of collagen fibers in living tissue when the light is applied to the living tissue is larger than a temperature rise width of water containing cells that are contained in the living tissue and that are present around the collagen fibers; and applying a pulse of light with the set wavelength to the living tissue to heat the living tissue.

Abstract: An optical fiber state detection system includes: a first light source that outputs a monitor-related light for monitoring a state of an optical fiber; a reflection mechanism that reflects the monitor-related light propagated through the optical fiber; a light receiving part that receives a reflected light reflected by the reflection mechanism; a tap coupler provided between the reflection mechanism and both the first light source and the light receiving part such that the first light source and the light receiving part are connected the tap coupler; and a control part. Further, when the control part detects that a received optical power of the reflected light is greater than 0 and lower than a predetermined threshold value, the control part outputs information on a decrease in the received optical power to outside.

IPC: G02B6/44
Abstract: A method for manufacturing an intermittent bonding type optical fiber ribbon which is capable of forming non-connection portions and intermittent connection portions between adjacent coated optical fibers formed into an optical fiber ribbon by performing a laser processing for the ribbon through irradiation with a pulse laser light, thereby making it possible to rapidly form the intermittent connection portions and the non-connection portions while maintaining high linear velocity of the coated optical fiber. The non-connection portions and the intermittent connection portions are formed in the obtained intermittent bonding type optical fiber ribbon through the irradiation with the pulse laser light, so the intermittent bonding type optical fiber ribbon becomes the intermittent bonding type optical fiber ribbon, which is capable of securing operability during collective connection and surely being subjected to an intermediate branching without damaging cable characteristics during high density mounting.

Abstract: An optical probe includes: an optical fiber; a reflecting portion; and a traveling direction changing portion changing a traveling direction of a laser beam of a first wavelength that has transmitted through the reflecting portion to a direction different from a traveling direction before transmitting through the reflecting portion. Further, the traveling direction changing portion is configured by a bending structure having a structure in which a portion on a distal end side of the optical fiber is bent, and the reflecting portion is provided closer to a proximal end side of the optical fiber than the bending structure.
