Dysprosium mid-infrared lasers: current status and future prospects
R. I. Woodward, M. R. Majewski, S. D. Jackson
With growing interest in the mid-infrared spectral region, dysprosium has recently been revisited for efficient high-performance infrared source development. Despite historically r…
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…
Ultrafast mid-infrared fiber laser mode-locked using frequency-shifted feedback
M. R. Majewski, R. I. Woodward, S. D. Jackson
We demonstrate ultrashort pulse generation from a fluoride fiber laser co-doped with holmium and praseodymium. To date the majority of work focused on short pulse generation from t…
Q-switched Dy:ZBLAN fiber lasers beyond 3 μm: comparison of pulse generation using acousto-optic modulation and inkjet-printed black phosphorus
R. I. Woodward, M. R. Majewski, N. Macadam +4
We report high-energy mid-infrared pulse generation by Q-switching of dysprosium-doped fiber lasers for the first time. Two different modulation techniques are demonstrated. Firstl…
Mode-locked dysprosium fiber laser: picosecond pulse generation from 2.97 to 3.30 μm
R. I. Woodward, M. R. Majewski, S. D. Jackson
Mode-locked fiber laser technology to date has been limited to sub-3 μm wavelengths, despite significant application-driven demand for compact picosecond and femtosecond pulse sour…
Emission beyond 4 μm and mid-infrared lasing in a dysprosium-doped indium fluoride (InF3) fiber
M. R. Majewski, R. I. Woodward, J. -Y. Carreé +3
Optical emission from rare-earth-doped fluoride fibers has thus far been limited to less than 4 μm. We extend emission beyond this limit by employing an indium fluoride (InF3) glas…
Dysprosium-doped ZBLAN fiber laser tunable from 2.8 μm to 3.4 μm, pumped at 1.7 μm
M. R. Majewski, R. I. Woodward, S. D. Jackson
We demonstrate a mid-infrared dysprosium-doped fluoride fiber laser with a continuously tunable output range of 573 nm, pumped by a 1.7 μm Raman fiber laser. To the best of our kno…
Wideband saturable absorption in few-layer molybdenum diselenide (MoSe2) for Q-switching Yb-, Er- and Tm-doped fiber lasers
R. I. Woodward, R. C. T. Howe, T. H. Runcorn +4
We fabricate a free-standing molybdenum diselenide (MoSe2) saturable absorber by embedding liquid-phase exfoliated few-layer MoSe2 flakes into a polymer film. The MoSe2-polymer com…
