摘要: Using the photonic crystal fiber with the zero dispersion wavelength of the fundamental mode at 780 nm designed and fabricated in our lab, the ultra-violet and mid-infrared continua are generated by cross-phase modulation between red-shift solitons and blue-shift dispersive waves. The dependences of continuum on the pump power and wavelength are investigated. With the pump working at 820 nm, when the pump power increases from 300 to 500 mW, the bandwidths of ultra-violet and mid-infrared continua change from 80 to 140 nm and 100 to 200 nm, respectively. The wavelength of ultra-violet continuum is below 246 nm, and the wavelength of mid-infrared continuum exceeds 2500 nm. Moreover, the influences of pump power on wavelength and conversion efficiency of different parts of continua are also demonstrated.
