Embodiment Construction

[0011] The optical fiber adopts a quartz optical fiber with a core diameter of 0.4mm, the synthetic beam condenser 11 adopts a lens with a diameter of φ15mm and a focal length F=16mm, and the homogenizing rod 12 adopts a K9 glass rod with a square cylinder of 6mm×6mm×60mm.

[0012] In the laser display, three optical fibers can be used to make the discrete-end optical fiber 8 and the bundled optical fiber 10, and the three cores in the bundled optical fiber 10 are arranged closely in the shape of a finished font. Red, green, and blue lasers are respectively input at the input ends of the three discrete-end optical fibers 8 , and the combined color light is output in parallel from the output end of the bundled optical fiber 10 . Because the three fiber cores in the bundled optical fiber 10 are arranged closely in the shape of a finished product, and the diameters of the three optical fibers are smaller (each 0.4mm), so the light emitted from these three fiber cores basically rec...

Abstract

The invention belongs to the laser video display field and relates to a kind of composing and homogenizing method of the multiple-beam laser. The ends of multiple optical fibers are at the same level and they are packed together to form a tight and parallel multiple-beam optical fiber. The multiple-beam laser can transmit respectively through the fiber cores of the optical fibers to form a beam of light to output. It is produced simply; the optical energy loss of laser is low; the coupling efficiency is high. The light transmitted through the multiple-beam optical fiber is homogenized by the light homogenizing system. It decreases the polarization and cohering of laser and makes sure that the lightness and the color of the laser display image are uniform and there is no intervening stripe.

Description

technical field [0001] The invention belongs to the field of laser video display and relates to a method for synthesizing multiple beams of laser light. Background technique [0002] In laser display, red, green, and blue lasers need to have higher power. For lasers, every increase in laser power will bring technical difficulties and high manufacturing costs, as well as power consumption, volume, life, and stability. Sex and many other issues. In addition, in laser display, it is often necessary to combine red, green, and blue laser beams into one laser beam to obtain white light or the color to be displayed. The way to solve these problems is to couple multiple laser beams into one beam to realize the coupling of multi-beam same-frequency lasers and non-same-frequency lasers to meet the needs of laser display. In multi-beam laser coupling technology, improving coupling efficiency is crucial. [0003] At present, multi-beam laser fiber coupling adopts bifurcated fiber, su...
