In this article

a highly nonlinear photonic crystal fiber with a pure silica core is designed and fabricated

of which the core diameter is 1.65μm

the air hole diameter 4.75μm

the space between the hole centers 5.35μm

the zero dispersion wavelength 1 120 nm and the dispersion at wavelength of 800 nm-88 ps/（nm.km）.Supercontinuum emission with a smooth spectrum stretching from 450 to 1 400 nm is obtained by injecting 30 fs Ti: sapphire laser pulses with an energy of up to 5 nJ

a pulse repetition rate of 100 MHz and a central wavelength of 800 nm into 2 meters of such a photonic crystal fiber.
