AI Technical Summary

Technical Problem

Existing fiber lasers contain too many pump source components, resulting in large module size, energy waste, and an inability to meet the application requirements of integration, miniaturization, and low cost.

Method used

An integrated pump source system is adopted, which combines collimating lens group, reflector and beam splitter to achieve high-precision shaping of pump light and beam focusing of multiple beams. The pump light is distributed according to a preset ratio by beam splitter to reduce device redundancy and meet the power supply requirements of laser resonator and laser amplification stage with a single module.

Benefits of technology

It significantly reduces the physical size of the laser system, lowers hardware costs, improves photoelectric conversion efficiency and system integration, and avoids pump light energy loss.

Abstract

This invention discloses an integrated pump source and system. The integrated pump source includes: a pump source for generating pump light; multiple collimating lens groups, each corresponding to a light source module, for collimating the pump light emitted by the corresponding light source module; a beam splitter disposed in the output light path of at least one of the collimating lens group, focusing lens, and reflector, for splitting at least one of the output light to form a first-level pump light and a second-level pump light; a reflector disposed in the output light path of the collimating lens group and / or the beam splitter, for deflecting and guiding at least a portion of the output light; a focusing lens disposed in the output light path of the reflector and / or the beam splitter, for focusing the output light; a first output pigtail for receiving the focused first-level pump light and outputting it outward; and a second output pigtail for receiving the focused second-level pump light and outputting it outward.
