Fiber grating uses the photosensitivity of optical fiber material: the germanium-doped silica optical fiber is illuminated through ultraviolet, space phasing optical grating is formed inside the fiber core, and a narrow-band (transmittance or reflection) wave filter or one optical fiber passive unit of reflector is formed in the fiber core.
(2) In the above formula, is the applied strain, is the Pockel piezoelectric coefficient of the elastic tensor of light, is the Poisson ratio, is the coefficient of heat expansion of optical fiber material, and is the temperature variation.

Technique of laser-TIG hybrid T-shape joint welding of titanium alloy Min Wang 1,a, Meiling Jiang 1,2,b, Qiang Wei1,c, Kanfeng Gu1,d 1Shenyang Institute of Automation, Shenyang, Liaoning Province, China 2Graduate School of the Chinese Academy of Sciences, Beijing, China amwang@sia.cn, bmljiang@sia.cn, cqwei@sia.cn, dkfgu@sia.cn Keywords: titanium alloy; T-joint; hybrid welding Abstract.
In the process laser beam can go through the level sheet and melt the legislative sheet to realize the penetration connection; by controlling the welding current, the arc at a certain angle with the level sheet and the laser beam provide the melting heat to produce the appropriate filler metal; the welded joints temperature Distribution and the pool profiles can be exactly controlled by the selection and configuration of laser hybrid welding parameters, so under the pool metals gravity, surface tension of molten material and the constraints of the jig equipment the welding foot can be achieved at the back bilateral side of T-shape joint.
In addition, as the laser spot acts on the back of TIG molten pool, the laser absorptivity of the material is extremely high to penetrate the work-piece with ease and a deeply penetrated weld seam is formed in the central line of the legislative board.

For example, spaceships can move long distances by using efficient electric engines, orbiting satellites can operate unlimited time periods without entry to Earth’s atmosphere, communication satellites can transfer a strong signal directly to customers, the International Space Station’s users can conduct many practical experiments and the global space industry can produce new materials.
As that is in science, the obstacles can slow, even stop, applications of these revolutionary innovations.
