Abstract

In order to output light beam of higher power and higher brightness

the fiber coupled diode laser module consisting 16 single emitter semiconductor laser diodes with 12 W was designed by ZEMAX. This module can produce 189.4 W from a standard optical fiber with core diameter of 100 m and numerical aperture of 0.22. The coupling efficiency is 98.6% and the brightness is above 94.66 MW/cm

-str. The new heat sink structure was designed by using SolidWorks software and the thermal analysis was simulated by ANSYS software. The results show that the hightest temperature of new heat sink structure is 42.4℃

1℃ lower than before.
