ABSTRACT:
A high-power pumping source for a three-level optical fiber amplifier includes a cladding-pumped four-level fiber laser. The four-level laser converts the high-power output of a diode array into an intense diffraction-limited beam which is utilized to pump an associated three-level laser. In turn, the output of the three-level laser is coupled to the fiber amplifier to supply a high-power pumping signal thereto.
