Compact Fully Integrated Alignment-Free and Linearly Polarized Ho Single-Frequency Waveguide Laser
Jeswin Jacob, T Toney Fernandez, Dale Otten +4
We report, for the first time, a fully integrated Ho-doped fluoride glass waveguide laser incorporating a femtosecond laser-inscribed waveguide and waveguide Bragg grating.…
Modeling Light Propagation and Amplification Efficiency in Highly Multimode, Yb-doped Fiber Amplifiers
D. L. Smith, K. Wisal, B. Huang +5
Multimode fibers have been proposed for mitigating nonlinear effects in high-power fiber amplifiers, allowing for significant power scaling. Most previous studies on light propagat…
Understanding the temperature conditions for controlled splicing between silica and fluoride fibers
Antreas Theodosiou, Ori Henderson-Sapir, Yauhen Baravets +5
This study explores the efficacy of thermal splicing conditions between silica and zirconium-fluoride fibers, focusing on achieving mechanical strength between the two fibers. A co…
Mitigating stimulated Brillouin scattering in multimode fibers with focused output via wavefront shaping
Chun-Wei Chen, Linh V. Nguyen, Kabish Wisal +9
The key challenge for high-power delivery through optical fibers is overcoming nonlinear optical effects. To keep a smooth output beam, most techniques for mitigating optical nonli…
In-fiber measurement of erbium-doped ZBLAN 4I13/2 state energy transfer parameter
Jillian E. Moffatt, Georgios Tsiminis, Elizaveta Klantsataya +4
Erbium-doped ZBLAN is the most commonly used glass for mid-infrared fiber lasers. In this paper we quantify the energy dynamics of the erbium ions which is important for improving…
Mode-locked and tunable fiber laser at the 3.5 m band using frequency-shifted feedback
Ori Henderson-Sapir, Nathaniel Bawden, Matthew R. Majewski +3
We report on a mid-infrared mode-locked fiber laser that uses an acousto-optic tunable filter to achieve frequency-shifted feedback pulse generation with frequency tuning over a 21…
Two-Photon Absorption and Saturable Absorption of Mid-IR in Graphene
Andrew Malouf, Ori Henderson-Sapir, Sze Yun Set +2
We report on the response of graphene to high intensity mid-IR radiation and show that graphene exhibits saturable absorption and significant two-photon absorption in the spectral…
Numerical Modeling of 3.5 micron Dual-Wavelength Pumped Erbium Doped Mid-Infrared Fiber Lasers
