Cladding pumped Q-switched fiber laser using a tapered fiber saturable absorber

We report a passively Q-switched all-fiber laser using a large mode area Yb
³⁺
-doped fiber cladding-pumped at 915 nm and an unpumped single-mode Yb
³⁺
-doped saturable absorber fiber. 60 μΐ 80 ns pulses at 1030 nm are reported.
