All-solid antiresonant fiber design for high-efficiency three-level lasing in ytterbium-doped fiber lasers

We propose and investigate an all-solid ytterbium-doped antiresonant fiber (YbARF) design to inherently suppress four-level lasing with >20 dB/m of selective loss and achieve high-efficiency three-level lasing while maintaining near-diffraction-limited operation with an ultra-large mode area of a...
