Goodno G, Rothenberg J
Opt Express
. 2019 May;
27(9):13129-13141.
PMID: 31052842
We demonstrate a modulation approach that relaxes the limitations imposed by stimulated Brillouin scattering (SBS) on amplification and propagation of narrow-linewidth light in fibers. By imposing synchronous amplitude and phase...

Goodno G, Rothenberg J
Appl Opt
. 2016 Nov;
55(29):8335-8337.
PMID: 27828082
Nelson et al. [Appl. Opt.55, 1757 (2016)APOPAI0003-693510.1364/AO.55.001757] recently concluded that coherent beam combining and remote phase locking of high-power lasers are fundamentally limited by the laser source linewidth. These conclusions...

Thielen P, Ho J, Burchman D, Goodno G, Rothenberg J, Wickham M, et al.
Opt Lett
. 2012 Oct;
37(18):3741-3.
PMID: 23041844
We demonstrate coherent beam combining using a two-dimensionally patterned diffractive optic combining element. Fifteen Yb-doped fiber amplifier beams arranged in a 3×5 array were combined into a single 600 W,...

Opt Lett
. 2012 Jul;
37(14):2832-4.
PMID: 22825149
Five 500 W fiber amplifiers were coherently combined using a diffractive optical element combiner, generating a 1.93 kW beam whose M(2)=1.1 beam quality exceeded that of the inputs. Combining efficiency...

Goodno G, Shih C, Rothenberg J
Opt Express
. 2010 Dec;
18(24):25403-14.
PMID: 21164888
Coherent combining efficiency is examined analytically for large arrays of non-ideal lasers combined using filled aperture elements with nonuniform splitting ratios. Perturbative expressions are developed for efficiency loss from combiner...

Goodno G, McNaught S, Rothenberg J, McComb T, Thielen P, Wickham M, et al.
Opt Lett
. 2010 May;
35(10):1542-4.
PMID: 20479802
A three-stage Yb-fiber amplifier emitted 1.43 kW of single-mode power when seeded with a 25 GHz linewidth master oscillator (MO). The amplified output was polarization stabilized and phase locked using...

Goodno G, Book L, Rothenberg J
Opt Lett
. 2009 Apr;
34(8):1204-6.
PMID: 19370118
A chain of four Tm-doped fibers amplified a single-frequency, 2040 nm diode laser to 608 W with M(2)=1.05+/-0.03, limited by available pump power. Stimulated Brillouin scattering limits were investigated by...

PMID: 16642058
A novel phase-only sampled 45 channel fiber Bragg grating (channel spacing, 100 GHz) with high interchannel and intrachannel reflection uniformity and precise dispersion matching capability to an 80 km SMF-28...
