• H01S 3/101 Lasers provided with means to change the location from which, or the direction in which, laser radiation is emitted
• H01S 3/102 by controlling the active medium, e.g. by controlling the processes or apparatus for excitation
• H01S 3/105 by controlling the mutual position or the reflecting properties of the reflectors of the cavity
• H01S 3/106 by controlling devices placed within the cavity
• H01S 3/11 Mode locking; Q-switching; Other giant-pulse techniques, e.g. cavity dumping
• H01S 3/13 Stabilisation of laser output parameters, e.g. frequency or amplitude
