Abstract

Modules consisting of multiple single emitters pose demanding challenges on assembly, production capabilities and cost. A fiber coupled module has been produced delivering 100 W optical power from a 105 μm, NA 0.15 fiber. The module consists of two times six vertically stacked single emitters combined by polarization multiplexing. Special attention was paid to the development of a very robust low cost pigtail. The developed semiautomatic highly accurate process enables assembly times way faster than possible in a purely manual procedure. The achievable yield in combination with low material costs proofs the excellent potential for the manufacturing of cost efficient laser modules.
