• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

The invention discloses a pulse string generation device for polarization coherent beam combination and a polarization coherent beam combination system, and belongs to the technical field of pulse generation, the pulse string generation device sequentially comprises a first acousto-optic deflection unit, a polarization direction adjusting assembly and a second acousto-optic deflection unit, and the first acousto-optic deflection unit, the polarization direction adjusting assembly and the second acousto-optic deflection unit respectively perform beam splitting regulation, polarization modulation and beam combination on incident laser pulse strings. Outputting a pulse train having a specific polarization mode to generate a single pulse; the internal structure enables the whole system to be more flexible and controllable, and the cost is reduced. Wherein the propagation direction of the incident pulse can be regulated and controlled by changing the modulation sound wave frequency of the acousto-optic deflection
