1.Product description
The specification is specially for EFC8-Q product, it's a water-direct(WD) cooling structurer, Lasfiberio has another water-indirect(WID) cooling structurer as optional, the WD structurer has a better cooling effect but has requirement for water quality compare to WID one.
At the input and output fiber end face in high power (hundreds, thousands even dozens of thousand watts) laser, the energy density can be very high . So if the laser radiation transmits to the fiber end face, there is high risk of fiber burning or degradation.
A endcap at the end face of fiber is a good solution for above issue - an 8mm diameter endcap spliced to the fiber can greatly increase the diameter of the beam spot, which is a very effective method to lower the power density.
On the surface of the endcap, a high damage threshold AR coating is coated, while on the other side of the fiber, a high efficient cladding power stripper (CPS) is added, most important it's epoxy-free.
2. Features
¡Ñ Fiber spliced to 8mm end cap, passed proof test & vibration test.
¡Ñ A cladding power stripper (CPS) is made near the end cap, featured in high stripping efficiency, low loss in fiber core, epoxy free.
¡Ñ Safety interlock.
¡Ñ High damage threshold AR coating on the surface of end cap can decrease transmission loss.
¡Ñ Compatible interface: QBH, LLK-Q, HLC-8/LC-8
3.Applications
¡Ñ Output of fiber Laser
¡Ñ Solid state Laser and fiber coupled diode Laser
¡Ñ Accessories of Laser machine
