Bare Fiber Coating

Bare Fiber Coating means laying optical thin film on the bare fiber end face to increase light transmission or reflection.

3V TECHNOLOGY succeed in polishing bare fiber without any epoxy and coating optical precision thin film to the fiber tip,which improve the product quality significantly.

Product Application:

-Fiber laser pump diode coupling
-High power laser processing flexible transmission

-Fiber optic Sensor(Connecting Photoelectric detector)

Product Features:

-The fiber tip is directly polished without any epoxy in the process,which can aviod laser absorption caused by epoxy residue and reduce the fiber burn rate efficiently.
-High quality fiber tip polishing surface,without scratches and particles on the fiber core.-Coat only on the bare fiber tip(without ferrule&epoxy),which can eliminate film cracking caused by inconsistent thermal expansion coefficients of different substrates under the coating layer.
-Avoid the impact of the ferrule and epoxy on the laser chip at a close distance,effictively reducing COD and chip Contamination.
-Low heat absorption and high laser damage threshold of coating layer,Optical damage threshold(＞200MW/cm2,test by quantel USA)

Fiber Pigtail Coating

Protruding fiber pigtail is a kind of assembly which install a ceramic ferrule to the end of the coated bare fiber and keep the fiber’s endface some distance from the ferrule’s endface.Different from the traditional fiber and ferrule flat assembly way.Protruding fiber pigtail can eliminate film cracking caused by inconsistent thermal expansion coefficients of different substrates(fiber,epoxy,ferrule) under the coating layer and has obvious advantage in fiber coupled high power laser diode.

Product Application:

-Fiber laser pump diode coupling.
-High power laser processing flexible transmission.
-Medical laser equipment coupling transmission .
