Abstract

A tricolor laser that the high-power red, green and blue of the side pump operate together, the horizontal light-path of the plano-concave total reflection lens sets the acousto-optic Q switch, the laser crystal, the first beam lens, the second beam lens, the two-time harmonic lens, the third frequency multiplication crystal, the third plane reflector; the one side of the first beam lens facing the vertical light-path sets the first frequency multiplication crystal, the first plane reflector, the forth plane reflector setting on the other side of the first beam lens in turn; the one side of the second beam lens facing the vertical light-path sets the second frequency multiplication crystal, the second plane reflector, the fifth plane reflector setting on the other side of the second beam lens in turn. The invention can achieve the tricolor laser output of the high-power density red, green and blue.

Description

technical field [0001] The invention relates to a multi-wavelength solid-state laser, in particular to a side-pumped high-power red, green and blue three-primary-color laser device operating simultaneously. Background technique [0002] Since the birth of the world's first ruby ​​laser in 1960, all kinds of lasers and laser technology have developed rapidly. Among them, the development of multi-wavelength lasers, especially red, green and blue three-color lasers, has attracted much attention. The reason is that it overcomes the defect that lasers output a single wavelength, and has broad market and application prospects in many fields, such as large-screen laser TVs, laser color displays, laser entertainment performances, and laser manufacturing. The red, green and blue primary color laser display is the latest technology in the field of projection display. It has more advantages than other display technologies: super large screen, high brightness, wide color gamut, highly s...
