Abstract

The paper introduces a research on fiber coupled CW diode laser module. It works in a series connection other than parallel connection, which is done by other devices. Through the study and optimization on technology of heatsink insulate, narrowband reflector, exact coupling compound and collimation, we have secured 10~20W output power from fiber which have 100µm core diameter when the working current is only several ampere. Because the total junction capacitance in series connection is small, it is easy to carry out narrower pulse direct modulation .All of these characters make it more suit the arm equipment which use batteries to power supply. Especially in these fields such as laser beam riding guidance, active image and night vision system, it may have good foreground.
