Embodiment 1

[0023] Such as figure 1 , 2 Shown: a laser dazzler, which has a housing 1, in which a laser driver 2, a laser module system 4, an optical mirror system 5, and a fiber coupler are installed in the order of the laser propagation path from front to back 6. And optical fiber adapter 7; Described laser module system 4 comprises the green laser module 4.1 that is respectively connected with laser driver 2, blue laser module 4.2 and red laser module 4.3; Described optical mirror system 5 comprises: 45 ° Dichroic mirror 5.1, 45 ° blue light reflector 5.2, 45 ° reflector 5.3, and 45 ° trichromatic mirror 5.4; the 45 ° dichroic mirror 5.1 is installed on the light path of green laser module 4.1; blue light reflector 5.2 is installed on blue On the optical path of the laser module 4.2, the reflected light of the 45° blue light reflector 5.2 is incident on the 45° dichroic mirror 5.1; the 45° reflective mirror 5.3 is installed on the red laser module 4.3 optical path, and the reflected l...

Embodiment 2

[0025] The difference from the above-mentioned embodiment is: the laser wavelength of the semiconductor laser 11 of the green laser module 4.1 is selected from 1064nm in the 1000nm series; the laser wavelength of the semiconductor laser 11 of the blue laser module 4.2 is selected from 976nm in the 900nm series; The laser wavelength of the semiconductor laser 11 of module 4.3 is selected from 650nm in the 600nm series.

[0026] Further explain the structure and working principle of the laser module as follows:

[0027] Taking the green laser module 4.1 as an example, the green laser module consists of a 1064nm semiconductor laser 11, a ball lens 12, a ball lens 13, a MgO:PPLN module 14, a shaping lens 15, an optical filter 16 and a temperature control base 17. The 1060nm semiconductor laser 11 is a 1064nm DBR semiconductor laser working at 60°C. Its emitted laser light is coupled to the MgO:PPLN module through ball lenses 12 and 13 for 14 frequency multiplication. Coated with ...

Abstract

The invention relates to a laser dazzler, which is widely applied to occasions such as caution, guarding, inspection and public security. The laser dazzler is provided with a shell; a laser driver, a laser module system, an optical lens system, an optical fiber coupler, and an optical fiber adaptor are arranged in the shell from front to back in turn according to a laser propagation path; the laser module system comprises a green laser module, a blue laser module and a red laser module which are respectively connected with the laser driver; the optical fiber coupler is connected with the optical fiber adaptor through an optical fiber; and the optical fiber adaptor is also connected with a laser transmitter through an optical fiber. The laser dazzler has the advantages that: the laser dazzler can independently or alternately output green, blue and red laser with three lengths, and has good anti-glare capacity; and compared with a semiconductor pump laser, the laser dazzler has the advantages of reducing the complexity of a temperature control system and the power consumption, and having long working time and high electronic-optic efficiency.

Description

technical field [0001] The invention relates to a laser dazzler, belonging to the technical field of lasers. The laser dazzler is a non-lethal laser device, which can alternately or independently emit laser beams of three wavelengths to dazzle or warn suspicious persons at close range, and is widely used in warning, prevention, inspection, security and other occasions. Background technique [0002] Currently on the market, the laser dazzler whose laser power must be lower than the laser threshold of permanent damage to the human eye has the following disadvantages: [0003] 1. The wavelength of the laser used is 532nm, which is the most sensitive to human eyes. A single-wavelength laser dazzler is easily resisted by the opponent. If protective tools such as protective glasses are used to prevent the laser beam from reaching the human eye, this will reduce the impact of the laser dazzler on people. The dazzle effect of the eye cannot even dazzle; [0004] 2. The 532nm laser...
