Using the hollow-core photonic crystal fiber (HC-PCF) with the zero dispersion wavelengths of fundamental mode and second-order mode around 887 nm and 758 nm designed and fabricated in our lab, broadband supercontinuums (SC) from 180 nm to 1100 nm are efficiently generated in the ultraviolet and visible wavelengths by Ti: sapphire laser with working wavelength of 790 nm and pulse width of 120 fs. The influence of pump power on SC is also analyzed. The power ratio of the SC signal to the residual pump is calculated as 65:1, and the maximum conversion efficiency of 37% in the experiment is achieved..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
