3 High Power Fiber Laser System with Side Pumping Arrangement US13933175 2013-07-02 US20150007615A1 2015-01-08 Valentin Gapontsev; Igor Berishev; Nikolai Strougov; Vadim Chuyanov
A twin fiber laser arrangement is configured with active and passive fibers supporting respective signal and pump lights and a reflective coating surrounding the fibers along a section of the arrangement. The passive fiber has regions covered by respective protective layer and coating-free regions alternating with the layer covered regions, wherein the reflective coating is configured to overlap the protective layer which shields the end of the reflective coating from high power pump light.
4 Manufacturing method of glass fine particle deposit and manufacturing device JP2012148501 2012-07-02 JP2014009142A 2014-01-20 SUZUKI TOMOYA
PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device of a glass fine particle deposit capable of performing adjustment of manufacturing conditions easily while sealing a gap between a burner and a reaction vessel in a favorable sealing state for a long time.SOLUTION: In a state where a gap between a cylindrical burner fitting part 31 provided on a wall part of a reaction vessel 12 and a burner 15 inserted into the burner fitting part 31 is sealed in an air-tight manner by a seal member 35, glass fine particles generated by the burner 15 are deposited in the reaction vessel 12, so that glass fine particle deposit is produced. The seal member 35 comprises an elastic material having heat resistance of the operating temperature of the burner fitting part 31, and it has an annular shape mounted between the inside of the burner fitting part 31 and the outside of the burner 15. An inner peripheral part 38 being attached to the outer peripheral surface of the burner 15 is thinner than an outer peripheral part 37 being attached to the inner wall of the burner fitting part 31.
