Problems solved by technology

However, the parametric oscillator OPO pumped by the mode-locked laser requires synchronous pumping, which requires high mechanical length stability and accuracy of the laser resonator, reaching the order of microns, which is quite difficult to achieve.
Moreover, traditional lasers have problems in volume, stability, power consumption, etc., and it is difficult to reduce the cost

Abstract

The present invention relates to a red laser module used for the laser display, and the invention is characterized in that the module comprises at least two lasers which are coupled to a module with an array arrangement. As the invention adopts a colorful module which uses a plurality of semiconductor lasers with size 660nm+-10nm for array-coupling and outputs the high-power, the invention is more suitable to be taken as the light source of the laser television. The invention can satisfy the requirement of the laser television to facilitate the realization and the device is easy to be assembled. At the same time the producing difficulty and the producing cost are reduced.

Description

【Technical field】 [0001] The invention relates to a laser module, especially a red laser module used for laser display. 【Background technique】 [0002] TVs and color displays have become the necessities of modern life. Due to the huge potential and profits of this market, all countries are committed to the development of high-definition and large-screen displays to meet people's constantly updated needs for this product, such as: large-screen plasma display (PDP), liquid crystal display (LCD), etc. Using lasers as light sources for color displays is a trend in the development of laser technology, and it has always been the dream of researchers. With the successful development and launch of red, green, and blue three-color semiconductor lasers, the advent of laser TV has become possible, and it has become the most powerful competitor in the display market in the 21st century. [0003] However, the directionality of the laser is very strong, and the divergence of the beam is...
