“…The fiber laser scheme could also be very versatile. A reported wide waveband Yb-doped fiber laser was ranging from visible to near IR [3]. Based on the chirp FBGs, the fiber laser could acquire femtosecond duration pulse output [4], and the shortest duration pulse was sub-5 femtosecond [5].…”

A LD-clad-pumped single-end operation Tm-doped silica fiber laser was reported. The output center wavelength was located at nearly 1.96 μm, and the maximal output power was 2.41 W with a 7.2 W threshold and 37.7% slope efficiency respected to the launched pump power. The laser cavity was made up only by the multi-mode FBGs, which was directly written into the 25/250 μm double-clad Tm-doped multi-mode fiber core using an 800 nm femtosecond laser and a phase mask. There was no output coupler at the other fiber end, which was angle-polished (40.4 • ) to suppress the fiber end Fresnel reflection. The output power characteristics were investigated with variable anglepolished fiber end as output coupler, such as: 0 • , 5.4 • , 25.5 • , and 40.4 • . With the increasing of fiber end polished angle, the fiber laser output slope efficiency almost held invariable, and the fiber laser only had a increasing of threshold. The output laser spectrum had no change at different polished angles.

This paper reports an ytterbium-doped linear-cavity fiber laser with the optical length of 1.6 km passively modelocked by a high modulation depth semiconductor saturable absorber mirror (SESAM). An ultra-low repetition rate of 191 kHz was achieved. The laser delivered the highly-chirped output pulses with the energy up to 75.2 nJ.Intensity, a.u. Pulse spectrum of 400-m mode-locked ytterbium-doped fiber laser where the central wavelength was 1033 nm and FWHM is 3.5 nm

“…Ytterbium doping is attractive for high-power pumped fiber lasers because of its high efficiency and strong pump absorption [1][2][3][4]. Ytterbium-doped silica fibers exhibit very broad absorption and emission bands, from 800 nm to 1064 nm for absorption and 970 nm to 1200 nm for emission [5].…”

The performance of double-clad ytterbium-doped fiber laser with different pumping wavelengths

et al. 2009

View full text Add to dashboard Cite

Abstract:The effect of pumping wavelengths on the performance of double-clad Ytterbium-doped fiber laser (YDFL) is experimentally demonstrated. The YDFL is constructed using a fiber Bragg grating as wavelength selective filter in a linear cavity resonator. The YDFL operates at wavelength of 1064.4 nm with a bandwidth of 0.2 nm and signal to noise ratio of more than 30 dB. The efficiency of the YDFL is observed to depend on the absorption cross section spectrum of the YDF. The slope efficiencies of the YDFL are obtained at 60.4% and 67.5% for the pumping wavelengths of 937 nm and 967 nm, respectively. The threshold power to achieve lasing is approximately 0.5 W for both pumping wavelengths.
