随着半导体激光光源在激光加工领域的应用不断扩展
以激光二极管阵列制成的光纤耦合模块由于存在耦合效率低的缺点
已不能满足激光加工低成本的需求
因此研制高耦合效率的半导体激光器光纤耦合模块变得十分重要。本文将8只波长为808 nm、输出功率为5 W的单管半导体激光器通过合束技术耦合进光纤
制备了一种高效率的半导体激光器光纤耦合模块。光纤芯径为200 m、数值孔径(
N
A)为0.22
光纤输出功率为33.2W
耦合效率超过83%
这种高效率半导体激光器光纤耦合模块
可用于激光打标、塑料加工等领域。
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 meclical treatment fields.
