A multifunctional laser (10) which, in a first operational mode, outputs a mode-locked beam for vibration sensing applications and, in a second operational mode, outputs a Q switched illumination beam for imaging applications. The inventive laser (10) includes a resonant cavity (110, 120, 190); a gain medium (100) disposed with the cavity; a first arrangement (150) in communication with the medium for causing a Q-switched signal to be transmitted from the cavity; a second arrangement (180) in communication with the medium for causing a mode-locked signal to be transmitted from the cavity; and a mechanism (130, 140) for switching between the first arrangement and the second arrangement.
