OPTICAL FIBER HOLDING DEVICE AND LASER OSCILLATOR COMPRISING SAME

摘要

In order to efficiently radiate heat generated by an optical fiber, this device is provided with a holder 14, a holder retainer 15, and first and second indiums 18, 19. The surfaces of respective parts of the holder 14 and the holder retainer 15 abut on each other. Both the indiums 18, 19 are disposed between the holder 14 and the holder retainer 15 so as to sandwich an optical fiber 6 therebetween. The holder 14 has a first recessed portion 14b for housing the first indium 18, a first groove 14c, and a flat portion 14a. The first groove 14c is formed within the first recessed portion 14b and houses the optical fiber 6 sandwiched between both the indiums 18, 19. The flat portion 14a is formed in a portion other than that where the first recessed portion 14b is formed. The holder retainer 15 is formed to have a length covering the first recessed portion 14b and the flat portion 14a of the holder 14, and has a second recessed portion 15b for housing the second indium 19.
