Abstract
A table-top sized hybrid fluorescence spectroscopy system with picosecond, 3-MeV electron-beam from a photocathode and picosecond optical pulses was successfully demonstrated. This system has shown that the properties of an electron-beam pumped Ce:LiCAF: ultraviolet laser medium significantly differ from those of an optically pumped medium. The case of electron-beam pumped, the longer wavelength side of the spectrum is significantly enhanced and the fluorescence lifetime of this medium became slightly longer compared to the optically pumped case. This experimental results suggest that additional potential advantages of electron-beam pumping of Ce:LiCAF for an ultrashort pulse amplifier can be derived from its modified fluorescence spectral shape and longer lifetime.
