we first design the waveguide structure of a large-mode-field double-cladding Photonic Crystal Fiber(PCF) and then fabricate a high numerical aperture and large mode-field Yb3+-doped double-cladding PCF for the first time in China by using the patent technologies with our own IPR.The Numerical Aperture(NA) of its inner cladding is as high as 0.65
the NA of its fiber core 0.06 and its effective mode-field area 1 465.7 μm2.As far as we know
