Abstract

The invention discloses a pump source device, a laser source device and design methods thereof. The pump source device outputs hollow pump light, and comprises a ring laser array, a focusing lens, and an optical fiber. The ring laser array comprises multiple lasers distributed annularly, and is used to output multiple laser beams. The focusing lens includes one or more lenses, and is used to converge and couple the multiple laser beams into the optical fiber. The optical fiber is used to output pump light of which the spot intensity is in hollow distribution. The pump source device built according to the technical scheme provided by the invention is simple in principle and reasonable in configuration. Compared with the prior art, no additional light beam conversion element is needed, and the pump source device has the significant advantages of simple optical path, low building difficulty, high optical path stability, low cost, and high feasibility. The laser source device can be pumped by hollow pump light output by the pump source device to obtain hollow laser. The pump source device, the laser source device and the design methods thereof are of great significance to the fields of scientific research and production through use of hollow laser currently.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a pump source device, a laser source device and a design method thereof. Background technique [0002] For a long time, solid laser beams have been widely used in traditional laser processing industries such as cutting, cladding, welding and marking. With the continuous development of laser technology, in recent years, various laser beams with lower central intensity—— Hollow laser beams have been produced one after another. Hollow laser beams have broad application prospects in optical information processing, microelectronics, material science, biotechnology, medicine and other fields, which also promotes the further optimization of reflective beam forms in many traditional laser application fields. For traditional laser processing applications such as laser shock forming, hollow beams also offer certain advantages. [0003] There are two types of hollow laser beam generation. O...
