Description

High-power laser energy transmission converter

Technical Field

The utility model relates to an optics technical field, concretely relates to high-power laser energy transmission converter.

Background

The optical fiber has the advantages of good flexibility, small core diameter, low loss and the like, and the optical fiber connector plays a decisive role in laser energy transmission for application ends, such as cutting, marking, cladding, optical fiber laser pumping and the like, and particularly has outstanding advantages in energy transfer and spot size. The laser enters a use port through the connecting device and needs an introduction device like a water pipe connector, the introduction device is called a converter, the switching technology directly influences the laser energy transmission efficiency and is very important for use and application safety, and the conversion of the energy laser generally comprises mechanical installation and optical conversion. The mechanical conversion means that the end faces of two optical fiber connectors are infinitely close to each other or are bonded by optical cement, and high-efficiency conversion cannot be obtained no matter how close the end faces are close to each other because of a divergence angle of emergent light, and the effect of refraction loss added by the adhesive bonding is not satisfactory; most of optical conversion is performed by using a spherical mirror system or a G-LENS (self-focusing LENS), a matched intercept is selected for collimation or focusing, and influence factors of theoretical and processing aspects related to loss and defects brought by optical design cannot be considered thoroughly. The biggest problem of the prior art is that high-power transmission cannot be formed, only low-power or milliwatt-level signal transmission can be performed, damage to a system caused by heat accumulation cannot be overcome by physical butt joint or adhesion under high power, and the G-LENS cannot be used due to the fact that the G-LENS cannot transmit high power.
