As shown in Figure 1, the biography energy optical cable 100 for middle low power Laser Transmission described in one embodiment of the present of invention comprise energy-transmission optic fibre 10, the first energy-transmission optic fibre joint 20, by the spaced metallic sheath 30 of insulating medium and the second energy-transmission optic fibre joint (not shown).
Referring to Fig. 2 and Fig. 3, energy-transmission optic fibre 10 comprises fibre core 11 and covering 12, and the outside surface 12a of covering can process through frosted.At the energy-transmission optic fibre 10 that passes optically-coupled end that can optical cable 100 of the present invention (, the clear glass end cap that will describe below and the fiber section between sheet metal) the outside surface of covering 12 light scattering pipe 13 is set, light scattering pipe 13 can for example, be made by glass tube (quartz ampoule), its refractive index is greater than or is approximately equal to the refractive index of the covering 12 of optical fiber 10, and its outside surface 13a processes through frosted.Light scattering pipe 13 can be bonded together by bonding agent 14 with the covering 12 of energy-transmission optic fibre 10.
Referring again to Fig. 1 and Fig. 2, the first embedded energy-transmission optic fibre joint 20 of one end of energy-transmission optic fibre 10 comprises metal tube 21, be fixed on hermetically clear glass end cap 22 in one end port of this metal tube 21, fix hermetically sheet metal 23 in the other end port of this metal tube, closely around the heat radiator 27 of the outer wall setting of metal tube 21 and be arranged on the temperature sensor 28 in metal tube 21 outer walls.
Extend through sheet metal 23 and in grass tube 24 inside along the axis of metal tube 21 described one end of energy-transmission optic fibre 10, the end face of this end and 22 couplings of clear glass end cap.In addition, as mentioned above, in the part between clear glass end cap 22 and sheet metal 23 of this end of energy-transmission optic fibre 10, closely overlap and have light scattering pipe 13.
In the first described energy-transmission optic fibre joint 20, according to some embodiments of the present invention, metal tube 21 and sheet metal 23 can be made by metal or metal alloy such as copper, aluminium or stainless steel in the above.
According to some embodiments of the present invention, clear glass end cap 22 can be quartzy end cap, and it can be fixed in the port of one end of metal tube 21 hermetically by bonding agent 22a.The end face 22b of one end of clear glass end cap 22 can be coated with antireflection film, the exit end (not shown) coupling of this end face 22b and laser instrument.The end face 22c of the other end of clear glass end cap 22 can with the end face coupling of described one end of energy-transmission optic fibre 10, the side surface 22d of this end can carry out frosted processing.
