We report on a high-power single-frequency mode-hop-free fiber distributed Bragg reflector (DBR) laser fabricated from Tm-doped photosensitive alumino-silicate fiber and in-band pumped by an Er/Yb fiber laser at 1565 nm. The fiber DBR laser yielded up to 580 mW of single-frequency single-ended output at 1943 nm for ~ 5 W of absorbed pump power. Further scaling of the DBR laser output power was achieved...
We review the latest advances and developments in the area of single-frequency fibre lasers, their design and approaches for achieving power levels in excess of 100W. Future directions and applications of the technology will also be discussed.
Stable single frequency two-micron lasers are attractive sources for numerous application areas, including spectroscopy, gas sensing and nonlinear frequency conversion. In this paper we report on a Tm-doped silica fibre laser, based on a short cavity distributed Bragg reflector (DBR) design, employed in a simple master- oscillator power-amplifier configuration to produce 2.8 W of stable, linearly-polarised...
A Tm-doped fiber master-oscillator power-amplifier system that generates over 100 W of single frequency output in a near-diffraction-limited beam with an M2 parameter of 1.25 is described. The prospects for further increase in power are considered.
Thulium-doped silica fiber lasers and amplifiers offer a route to very high average power in the two-micron wavelength regime. This presentation reviews recent progress and considers the prospects for further improvement in performance.
