Piezoelectric stack driver array body, adjustable optical mirror and laser device

The present invention relates to a piezoelectric stack driver array body, an adjustable optical mirror, and a laser device, the piezoelectric stack driver array body comprising a base body and a piezoelectric stack driver array, the piezoelectric stack driver array comprising active piezoelectric stack driver units and inactive structural body units, the active piezoelectric stack driver units and the inactive structural body units are periodically mixed and arranged; the fixed end of the piezoelectric stack driver array is connected with the base body; an electrode of the piezoelectric stack driver unit is connected to an electrode end of the base body. The active piezoelectric stack driver units and the inactive structural body units are arranged in a mixed mode, the arrangement number of the piezoelectric stack driver units is greatly reduced, the manufacturing cost is remarkably saved, and the optical effect at least the same as the optical effect in the prior art is achieved. And the number of electrode
