    Abstract:

    A high-linear birefringence photonic crystal fiber is pumped by a femtosecond laser pulse generated by Ti: sapphire laser. The center wavelength of the pulse is 820 nm, which is located in the anomalous dispersion region of the photonic crystal fiber near zero dispersion. Experimental results show that the central wavelength of soliton is red shifted while that of dispersion wave is blue shifted into the visible wavelength with the increase of pump power. When the average power of the pump is increased to 0.45 W, the ratio of the dispersive wave to the residual pump intensity can be up to 42.67, while the spectral width of dispersion wave is broadened to 81 nm as well as the soliton bandwidth to 231 nm. Near infrared broad soliton and the highly efficient dispersive wave in the visible region was generated in the high nonlinear photonic crystal fiber, which provides an important reference for the frequency conversion and spectral broadening of the femtosecond laser.
