Background
The double-clad fiber grating is a core component of the fiber laser, and the photosensitive characteristic of the double-clad fiber needs to be increased when the double-clad fiber grating is manufactured. The high-pressure hydrogen-carrying device can enable the optical fiber to have photosensitive characteristics, and the hydrogen-carrying device enables hydrogen molecules to be doped into the core of the optical fiber at high pressure to improve the photosensitive characteristics of the optical fiber. As the diameter of the single-mode optical fiber is only about 250 micrometers, the traditional hydrogen carrying device can carry hydrogen on the single-mode optical fiber.
The existing single-mode optical fiber hydrogen carrying method is that a plurality of optical fibers are respectively placed in a seamless steel tube with the inner diameter of 6 mm, and the seamless steel tube is subjected to high-pressure hydrogenation treatment after two ends of the seamless steel tube are sealed. The traditional hydrogen carrying device can meet the requirement of high-pressure hydrogenation because the diameter of the single-mode optical fiber is thin, but for the double-clad optical fiber, the outer diameter is about 550 micrometers, the pressure is needed to be higher when carrying hydrogen, but the seamless steel pipe cannot bear higher pressure,

When the double-clad optical fiber carries hydrogen, the double-clad optical fiber needs to be placed in a winding ring due to the long length, when the number of the winding rings is large, the optical fiber is easy to loosen in the hydrogen carrying process, and the optical fibers of different types are easy to be disordered when being placed, so that the classified placement of the hydrogen carrying is not facilitated; when carrying hydrogen, the double-clad optical fiber is easy to extrude and can not fully contact with hydrogen molecules, so that the hydrogen carrying time of the double-clad optical fiber is longer.
