Fiber processing

Fiber processing, also known as end preparation, fiber-optic technology is the key process, including follow-stripping, cleaning and cutting the three links.Directly affect the quality of end-pumped optical fiber laser coupling efficiency and laser output power. 

An optical fiber coating stripping 
Optical fiber coating removal is the first step in face processing. Blade can be used strippers and strip the two methods. When using wire strippers strip, the left thumb and index finger pinch fiber, the exposed length of about 5cm, ring finger and little finger over fiber between the natural bent, in order to increase efforts to prevent slipping, strippers should be perpendicular to the fiber , the direction of the tilt within a certain angle, then gently stuck fiber jaw, right along with hard, flat along the fiber axial introduction to the whole process to be natural and smooth, for a success; when using the blade strip, the first with concentrated sulfuric acid soaking 3 ~ 5cm long fiber ends 1 to 2 minutes, wipe clean with alcohol cotton [2]. Left hand clenched fiber, fiber to maintain peace, to prevent slipping, the right hand with a blade to the end of the first direction along the fiber, and fiber into a certain angle, in turn strip the surface layer of polymer coating materials, this approach overcomes the use of chemicalsolvent for a long time soaking fiber corrosion serious shortcomings, and more than directly with the stripper or scrape blade is easier to remove the cleaner, easy to damage the cladding side of the part. 

2 Clean the surface of the cladding 
Observe the optical portion of the cladding is stripped to remove all, if left to be removed, if a very small amount is not easy to strip the coating, dip cotton balls available amount of alcohol, while dipping, side erase. The level of cotton torn flat fan-shaped pieces, dip a little alcohol (compared to two-finger pinching no overflow is appropriate), folded into a V-shaped, covered grip has been stripped of fiber, wipe along the fiber axis, and strive to a successful, a Cotton with 2 or 3 times to change in time, every time you want to use different parts and levels of cotton, thereby enhancing the utilization of cotton, but also to prevent the cladding surface of the secondary pollution. 

3 Fiber Cut 
Cutting the fiber end preparation is the most critical step, precision cutter is the basis of quality, rigorous scientific practices is guaranteed. Common cutting knife cutter pen and desktop fiber cleaver. Use a pen knife cutting the fiber is cut, the fiber placed in the finger, the other end of the first hand-held knife at a distance of about 5mm in position along the fiber axis perpendicular to the direction of the fiber is cut, and then gently cut the ends off; using a desktopFiber cutter operation, first to clean the cutter blade, place the V-groove and optical fiber positioning plate, and adjust the cutter position to place stable.Smooth cutting action should be natural, not heavy, not anxious to avoid the fiber cut, bevel, burrs and cracks and other undesirable end-generation [3]. 
Surface cleaning and cutting time should be closely co-ordinated, not interval too long, especially not to have been prepared on the dirty end of the air. To move gently, to prevent collision with other objects.
