Problems solved by technology

The method of cutting laser grains by using the process of expensive integrated circuit equipment and the planar deposition or epitaxy process on expensive wafers will inevitably increase the manufacturing cost and will not be able to be used by the public in large quantities.
[0032] It can be seen that the above-mentioned existing laser diode manufacturing method and its light-emitting device obviously still have inconvenience and defects in the structure and use of the method and device, and need to be further improved urgently.
In order to solve the above-mentioned problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable method and method for the general laser diode manufacturing method and laser diode light emitting device. The structure can solve the above-mentioned problems, which is obviously a problem that relevant industry players are eager to solve

Abstract

The invention relates to a method for manufacturing a laser diode having a coaxial long linear structure and a luminous device thereof. In the method, a coaxial laser diode structurally grows to manufacture the coaxial long linear laser diode. Because of longer coaxial tubular active coating and more uniform built-in electric field, more initial luminescence photons and higher quantum efficiency can be provided to generate laser amplification effect of stronger stimulated luminescence. The method comprises the following steps: manufacturing a long linear coaxial laser crystal bar; and axially cutting the crystal bar into coaxial long linear laser diodes in equal segment length to avoid the material consumption cutting mode on a wafer. The high light with the same output direction is uniformly dispersed and derived by coaxial fluorescent fibers to synthesize a white light illumination device. The method and the device ensures a laser luminescence mode with higher light, more electricity conservation, longer service life and lower cost to become an electricity-saving lighting source of the century.

Description

technical field [0001] The invention relates to a coaxial long-line laser diode, in particular to a method for manufacturing a coaxial long-line laser diode with a special strong light for illumination and a light-emitting device thereof. Background technique [0002] Because of their small size, high efficiency, and ease of use, solid-state semiconductor light sources have become important products for optical communications, industrial sensing, and white light lighting energy saving. The light emitted by conventional light-emitting diodes is spontaneous emission (Spontaneous Emission) generated by the recombination of electrons and holes. Its phase, polarization, and radiation direction are inconsistent, and it is randomly generated light, so it is called incoherent light (Incoherent Light), such as Figure 1A Shown is a schematic diagram of an incoherent natural light emitting diode. The relative semiconductor laser uses a resonator (Cavity Resonator) to generate standin...
