PROBLEM TO BE SOLVED: To provide an optical feeding light source device that is able to maintain high cleanliness for an optical path and is excellent in maintenance, for a long period of time.SOLUTION: An optical feeding light source device 1 comprises a laser beam emitter 5 that has, in a hollow optical waveguide 2 whose inner face is a mirror face, a liquid phase 4 disposed in a gas phase 3 and emits a laser beam disposed in the liquid phase in the optical waveguide 2. Dust and so on, which have entered the optical waveguide 2 are moved downward in the gas phase and trapped by the liquid phase. Above the laser beam emitter 5, an upward flow is caused by heat generation of the laser beam emitter 5. Accordingly, above the laser beam emitter 5, dust and so on ride on convection current and move upward.EFFECT: Since dust and so on are prevented from accumulating on an emission part of the laser beam emitter 5, deterioration of a light source and transmission of a laser beam are prevented. Accordingly, energy decrease of an emitted laser beam is prevented.SELECTED DRAWING: Figure 1
【課題】長期に亘り、光路の清浄度を高度に維持できるメンテナンス性に優れた光給電用光源装置を提供する。【解決手段】光給電用光源装置1は、内面が鏡面である中空の光導波管2の内部に、気相3と接する液相4を有し、光導波管2内の液相中に配置されたレーザー光を出射するレーザー光発光器5を備える。光導波管2内に侵入した塵埃等は気相中を降下して液相により捕捉される。レーザー光発光器5の上方にはレーザー光発光器5の発熱により上昇流が生じるため、レーザー光発光器5の上方では、塵埃等が対流に乗って上昇する。【効果】塵埃等がレーザー光発光器5の出射部に堆積せず、光源の劣化及びレーザー光の透過が防止されるため、照射レーザー光のエネルギーが低下しない。【選択図】図1
