Scalar Nanosecond Pulse Generation in a Nanotube Mode-Locked Environmentally Stable Fiber Laser
R. I. Woodward, E. J. R. Kelleher, D. Popa +5
We report an environmentally stable nanotube mode-locked fibre laser producing linearly-polarized, nanosecond pulses. A simple all-polarization-maintaining fibre ring cavity is use…
Tm-doped fiber laser mode-locked by graphene-polymer composite
M. Zhang, E. J. R. Kelleher, F. Torrisi +7
We demonstrate mode-locking of a thulium-doped fiber laser operating at 1.94μm, using a graphene-based saturable absorber. The laser outputs 3.6ps pulses, with~0.4nJ energy and an…
Towards visible CW pumped supercontinua
B. A. Cumberland, J. C. Travers, S. V. Popov +1
We report a 1 um continuous wave pumped supercontinuum which extends short of the pump wavelength to 0.65 um. This is achieved by using a 50 W Yb fibre laser in combination with a…
29 W High Power CW Supercontinuum Source
B. A. Cumberland, J. C. Travers, S. V. Popov +1
A 29 W CW supercontinuum spanning from 1.06 to 1.67 um is generated in a short length of PCF with two zero dispersion wavelengths. The continuum has the highest spectral power dens…
2W/nm Peak-power All-Fiber Supercontinuum Source and its Application to the Characterization of Periodically Poled Nonlinear Crystals
B. A. Cumberland, J. C. Travers, R. E. Kennedy +2
We demonstrate a uniform high spectral brightness and peak power density all-fiber supercontinuum source. The source consists of a nanosecond Ytterbium fiber laser and an optimal l…
2.1 um CW Raman Laser in GeO2 Fiber
B. A. Cumberland, S. V. Popov, J. R. Taylor +3
We report on 33 % efficient generation of the first Stokes in a high concentration GeO2 fiber Raman laser pumped by a 22 W Thulium doped fiber laser. An output power of 4.6 W at 2.…
