Lasers provided with means to change the location from which, or the direction in which, laser radiation is emitted

Full Title

Lasers, i.e. devices using stimulated emission of electromagnetic radiation in the infrared, visible or ultraviolet wave range (semiconductors lasers H01S5/00) > Controlling the intensity, frequency, phase, polarisation or direction of the emitted radiation, e.g. switching, gating, modulating or demodulating > Lasers provided with means to change the location from which, or the direction in which, laser radiation is emitted
