| Research Abstract |
We have investigated spectrally-controlled fiber laser sources by photonic bandgap fibers (PBGFs) for yellow-orange high-power light sources. By inhibiting amplified spontaneous emission (ASE) at high-gain wavelengths, power scaling at the long-wavelength wing of the Yb gain band is enabled, that have not been possible in conventional lasers. An 1178 nm laser radiation with a 167 W output power and 61% slope efficiency, as well as a 589 nm laser radiation with a 14.5 W output power by second-harmonics generation have been demonstrated for the first time. An 1178 nm all-fiber fiber oscillator and a single-frequency source have been developed. We have shown PBGFs can suppress not only ASE but stimulated nonlinear scattering, that presents a great potential of the PBGF laser.
