Laser device with active glass-fiber e.g. for power and data transmission, includes optical system for coupling pump light into glass fiber

摘要

A laser device has a pump laser diode (102) for generating a pump light, a first optics system (109) for coupling the pump light into a glass fiber (110), a housing (105) for accommodating the pump laser diode (102), an active doped glass fiber (110) in which the active doped glass fiber (110) is capable of carrying out long-wave to short-wave light conversion.
