Laser focusing structure and product using structure

Abstract

The invention relates to the technical field of laser application, in particular to a laser focusing structure and a product using the structure. The laser focusing structure comprises a light amplifier and a spectroscope, wherein the light amplifier has an output end and an input end; the caliber of the output end of the light amplifier is greater than the caliber of the input end of the light amplifier; the light output by the output end of the light amplifier is transmitted and then projected onto the spectroscope; the light projected onto the spectroscope is at least partially reflected and transmitted to serve as input light which re-enters the light amplifier through the input end of the light amplifier and then is copied and amplified; and the light projected onto the spectroscope and not reflected by the spectroscope is focused after being transmitted by the spectroscope and is output for application. Through enlarging the caliber of the output port of the light amplifier, thepower bearing ability of the structure is improved; and through restraining the caliber of a feedback input port, the focusing effect is strengthened. The product using the laser focusing structure isone of a laser cutter, a laser engraving machine, a laser scanner and a nuclear fusion reaction ignition device.

Description

technical field [0001] The invention relates to the technical field of laser application, in particular to a laser focusing structure and products using the structure. Background technique [0002] Laser is known as the fastest knife, the most accurate ruler and the brightest light. The application of laser is inseparable from the focusing of the laser beam. The traditional focus of the laser beam mainly uses a lens to transform and project the laser beam, including the use of optical fiber for transmission, so as to achieve the effect of focusing and combining the laser beam. [0003] However, this type of method faces challenges when we need to focus the beam to a farther and smaller area, especially when it is necessary to combine and focus the beams output by multiple devices into an extremely small area. For example, in the nuclear fusion laser ignition scheme, an expensive, large, sophisticated and complex system is used to meet this challenge, but it may not be able...

[0003] However, this method faces challenges when we need to focus the beam to a farther and smaller area, especially when it is necessary to combine and focus the beams output by multiple devices into a very small area.

For example, in the nuclear fusion laser ignition scheme, an expensive, large, sophisticated and complex system is used to meet this challenge, but it may not achieve good results
