• Protruding fiber pigtail 135/155 AR 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

    -High power laser test and measurement

    -Fiber Optic Sensor (Connecting photoelectric detector)


       ◆  Product feature     


    -The fiber tip is directly polished without any epoxy in the process, which can avoid 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 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, effectively reducing COD and chip Contamination. 

    -Low heat absorption and high laser damage threshold of coating layer, Optical damage threshold (> 200 MW/cm2, Test by Quantel USA,)
