OPTICAL FIBER FOR PUMP PROTECTION AND PUMP LIGHT SOURCE HAVING THE SAME AND BEAM COMBINER AND FIBER LASER |
摘要 |
PURPOSE: A pump light source-protective optical fiber, a pump light source, a beam combiner, and an optical fiber laser are provided to efficiently protect the pump light source by adding Sm ion having a high light absorption rate around a laser oscillating frequency in a range between 1030-1110 nm and 1165-1610 nm. CONSTITUTION: A plurality of pump light sources (1) are composed of diodes (LD). A beam combiner (2) connects an input unit optical fiber (3) with an output unit optical fiber (4). A beam combiner output unit optical fiber (5) is connected with a gain fiber through a fiber Bragg grid (FBG). The output light of the diodes collected through the input unit optical fiber is delivered to a gain fiber and a laser light is oscillated by using a rare earth ion-added optical fiber. An optical fiber (100) is connected between the output unit optical fiber and the input unit optical fiber. |
