In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] See also Figure 1 , the figure shows a separate long-distance adjustable focus laser dazzling device.

[0019] The laser dazzling device adopts a separate design. The laser dazzling device includes: a laser 1 and an emission window 2. The laser 1 is separated from the emission window 2.

[0027] The lens unit is composed of or mainly consists of a laser collimator lens group, a zoom lens group and a focusing mechanism. The laser beam of the laser 1 passes through the laser collimator lens group and the zoom lens group in sequence and then emits outward. The laser collimator lens group is used to collimate the laser beam of the laser 1. The zoom lens group is used to determine the divergence angle of the laser beam of the laser 1. The focusing mechanism is used to shift the zoom lens group and / or the compensation lens group in the zoom lens group to adjust the divergence angle of the laser beam. Preferably, the lens unit is configured so that the divergence angle of the laser beam is continuously adjustable in the range of 1mrad-30mrad.

[0028] In one embodiment, the laser 1 has a rectangular connector 12 and the emission window 2 has a circular connector 24. Both the rectangular connector 12 and the circular connector 24 are used for power and data transmission between the laser 1 and the emission window 2.

The laser dazzling method comprises: Based on the size and distance information of the dazzling target, the laser parameters of the laser dazzling device are determined, and the laser dazzling device is used to illuminate the dazzling target: an optoelectronic sighting device can be used to capture the dazzling target and determine the size and distance information of the dazzling target.

[0032] The laser parameters include: laser emission power, laser divergence angle and laser working mode. The laser working mode has continuous glare and stroboscopic glare. The frequency of the stroboscopic glare is, for example, 8 Hz.

[0033] Preferably, the laser dazzling method further comprises: Tracking the dazzling target, obtaining the dazzling effect on the dazzling target, and adjusting the laser parameters of the laser dazzling device based on the dazzling effect on the dazzling target: the optoelectronic sighting device can be used to track the dazzling target.

[0034] In one embodiment, the laser emission power is ≥ 20W and is continuously adjustable from 0 to 100%. When the laser emission power is equal to 20W, under the conditions of visibility of 10km and a spot diameter of 5m, the effective distance of the laser dazzling device can reach 5km.

[0035] In one embodiment, the laser intensity at the dazzling target position is 10uW / cm 2 -2.55mW / cm 2 .
