Problems solved by technology

[0003] At present, there have been a lot of research reports on the dual-wavelength laser output from a single laser, such as Nd:YVO 4 The laser can output 1064nm/914nm and 1342nm at the same time, and the Nd:YAG laser can output 1064nm and 946nm/1318nm at the same time. However, this type of laser usually improves the structure of the reson...

The adjustment mechanism 42 is connected to the multi-wavelength laser 41 for adjusting the height and angle of the output laser light of the multi-wavelength laser 41 .

[0055] The above-mentioned multi-wavelength laser 41 can be a dual-wavelength laser, and the dual-wavelength laser can output infrared laser or visible light laser. In this way, using the near-infrared band laser and the visible band laser for positioning and aiming can meet the requirements of all-weather use. The adjustment mechanism 42 may be an existing height angle adjustment device, which is not limited.

[0056] Those skilled in the art can clearly understand that, for the convenience and brevity of description, f...

Abstract

The invention provides a multi-wavelength laser and a laser sight and relates to the technical field of a laser. The multi-wavelength laser comprises a plurality of laser assemblies arranged in parallel, and a collimating lens. Each laser assembly comprises a pump light source, a coupling lens and an optical fiber. The pump light source, the coupling lens and the optical fiber are arranged coaxially in sequence along light output direction. Each laser assembly outputs one wavelength of laser. The collimating lens is used for collimating the laser output by each laser assembly to enable the laser output by each laser assembly to be output coaxially. The multi-wavelength laser and the laser sight can simplify the structure of the laser, reduce cost and improve ambient temperature adaptability and wavelength selectivity.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a multi-wavelength laser and a laser sight. Background technique [0002] A laser is a device that emits laser light. Coaxial dual-wavelength lasers have a wide range of practical applications, such as gun sights (sights). Some gun sights require to emit near-infrared band lasers at night and visible band lasers during the day, and use both near-infrared band lasers and visible band lasers for positioning and aiming, which can meet the requirements of all-weather use. [0003] At present, there have been a lot of research reports on the output of dual-wavelength lasers from a single laser, such as Nd:YVO 4 The laser can output 1064nm / 914nm and 1342nm at the same time, and the Nd:YAG laser can output 1064nm and 946nm / 1318nm at the same time. However, this type of laser usually improves the structure of the resonator, which is difficult to design and requires strict film system de...
