摘要
The ultraviolet continuum generation in the fundamental mode of photonic crystal fibers designed and fabricated in our lab are experimentally demonstrated. When the pump works in the normal dispersion regions of 780 nm and 830 nm, and the average powers increase from 100 to 500 mW, anti-Stokes signals can be efficiently generated based on the phase-matched degenerate four-wave mixing. The cross-phase modulation between the pump and the generated anti-Stokes signals can effectively extend the continuum into the ultraviolet wavelength range. This can provide an efficient light source for ultraviolet photonics and spectroscopy.
