摘要
Abstract
With the increase of LD application in the field of laser processing, the efficiency of the fiber coupled modular based on diode laser arrays is rather low, which can not meet the need of low costing for laser processing, so it is very important to develop a higher efficiency modular of fiber coupled diode lasers. In this paper, we achieved a higher efficiency fiber coupled module based on 8 single emitter diode lasers providing more than 32. 4 W output power from a 200 microns fiber core with an numerical aperture; NA) of 0. 22 at 808 nm. Power of each LD can reach to 5 Watts at operation current. More than 83% coupling efficiency of the modular has been realized. This high power LD module can be used in laser plastics processing and laser medical treatment fields.关键词
