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 > Stabilisation of laser output parameters, e.g. frequency or amplitude > by controlling the mutual position or the reflecting properties of the reflectors of the cavity
