this paper investigates coupling the laser light into a Photonic Crystal Fiber(PCF)by using a lens.It first conducts the modeling and analysis of the laser light and fiber model by using the ZEMAX software and designs a novel low-loss Photonic Band-Gap(PBG)infrared PCF for transmitting 10.6μm CO2 laser light.Then
it completes the coupling by using a ZnSe lens with the structural parameters of r1=11.39mm
r2=-25.43mm
thickness of 3mm and BFL =11.16mm and finds that the distance between the waist and the lens is 1 102.50mm
that between the image waist and the lens is 17.30mm and the coupling value is 94%.
