The first pulsed solid-state frequency-shifted-feedback laser as polychromatic laser guide star is reported. A Ti:Sa frequency-shifted-feedback (FSF) laser delivering a broad continuous spectrum in order to cover (after frequency mixing) the hyperfine-Doppler width of the 3S1/2 rarr4P3/2 transition at 330 nm is developed. The developed Ti:Sa laser can operate either in cw or pulsed mode. This new laser source has been characterized in terms of dynamic and spectral properties.
