Red and green laser module

Abstract

The invention relates to a red and green laser module which comprises a red laser and a green laser. The red and green laser module is characterized in that a piece of semi-transmission and semi-reflecting glass is arranged on the light path of the red laser, and a piece of reflecting glass is arranged on the light path of the green laser. According to the red and green laser module, red laser and green laser can be emitted at the same time through the combination of the reflecting glass and the semi-transmission and semi-reflecting glass.

Description

technical field [0001] The invention relates to a red-green laser module, which belongs to the field of optical equipment. Background technique [0002] The commonly used light sources are generally monochromatic light sources, but many applications require two-color light sources, and there is no module capable of producing two-color light sources in the prior art. Contents of the invention [0003] In order to overcome the defects in the prior art, the technical solution adopted in the present invention is: a red-green laser module, which includes a red laser and a green laser, and is characterized in that: a semi-transparent laser is set on the optical path of the red laser Semi-reflective glass, a piece of reflective glass is arranged on the optical path of the green laser. [0004] One side of the semi-transparent and half-reflective glass is coated with an anti-reflective 650 wavelength film, and the other side is coated with a reflective 532 wavelength film. [00...

AI Technical Summary

Problems solved by technology

[0002] The commonly used light sources are generally single-color light sources, but in many applications, two-color light sources are required. In the prior art, there is no module that can produce two-color light sources.
