The rise in output power from rare-earth-doped fiber sources over the past decade, via the
use of cladding-pumped fiber architectures, has been dramatic, leading to a range of fiber …

Efficient, narrow-linewidth Tm-doped fiber lasers operating in the 1.7 μm wavelength regime
are of significant importance for a wide range of applications. To achieve high-power 1.7-μm …

In this study, we report on a pure Kerr-lens mode-locked Yb: CaGdAlO_4 oscillator optically
pumped by a diffraction-limited fiber laser. At the repetition rate of 96 MHz, several …

We demonstrate that the strong 4-level Yb emission in a fiber laser can be almost completely
suppressed in an Yb all-solid double-clad photonic bandgap fiber, resulting in highly …

We propose a novel saddle-shaped Yb-doped fiber design for high power generation in the
spectral range near 0.976 μm. The fiber has a central single-mode part with a core diameter …

By using a high-brightness fiber pump laser, we demonstrate a pure Kerr-lens mode-locked
(ML) Yb: CaF_2 oscillator. The laser delivers 68 fs pulses with 2.3 W average power at 73 …

A 976 nm all-fiber Raman laser enabling high beam quality at direct multimode laser diode
pum** with low beam quality (M 2> 30) is demonstrated. The laser is performed in a …

Requirements on the double-cladding Yb-doped fiber (DCYF) for power scaling of diffraction-
limited fiber amplifiers are studied in this paper. By considering the limitations of thermal …
