Spatial mode switchable, wavelength tunable erbium doped fiber laser incorporating a spatial light modulator [PDF]

, 2014
We present a 2-mode group, switchable spatial mode erbium doped fiber laser incorporating a spatial light modulator. The laser wavelength can be tuned using an intra-cavity wavelength selective filter and provides >10dB extinction ratio between LP01 ...

Ten-watt-level 4.3 $\boldsymbol{\unicode{x3bc}}$ m-band nanosecond pulse generation in CO2-filled hollow-core fibers

High Power Laser Science and Engineering
A fiber-based route to mid-infrared nanosecond pulse laser generation in gas-filled hollow-core anti-resonant fiber at 4.3 μm with 10-W-level average power is demonstrated. The demonstration experiments, harnessing a single pump pulse with 37 ns duration

LD-Pumped Random Fiber Laser Based on Erbium-Ytterbium Co-Doped Fiber

Photonic Sensors, 2019
In this paper, a cladding-pumped erbium-ytterbium co-doped random fiber laser (EYRFL) operating at 1550 nm with high power laser diode (LD) is proposed and experimentally demonstrated for the first time.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Efficient fiber-laser pumped Ho:LuLiF₄ laser

We present results for an efficient Ho:LuLiF4 laser in-band pumped by a cladding-pumped Tm-doped silica fiber laser. The polarized, tunable Tm-doped silica fiber-laser operates at 1938 nm, ideally suited for in-band pumping the 40 mm long weakly-doped (0.

Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

Advanced Functional Materials, EarlyView.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

5.3 W/265 μJ Mid-IR All-Fiber Er³⁺:ZBLAN Gain-Switched Laser Based on Dielectric Fiber Mirror and Fiber-Tip Protection

Photonics
We report a 2.8 μm all-fiber high-power and high-energy gain-switched Er3+:ZBLAN laser based on dielectric fiber mirror and fiber-tip protection. The fiber pigtail mirror, specifically designed for dichroic operation (i.e., anti-reflection at 976 nm pump

Kilowatt Peak Power Pulses From a Passively Q-Switched Yb-Doped Fiber Laser With a Smaller-Core Yb-Doped Fiber as a Saturable Absorber

IEEE Photonics Journal, 2014
We demonstrated a passively Q-switched Yb-doped fiber laser in an all-fiber configuration that used a piece of a Yb-doped fiber with a smaller core than the gain fiber as a saturable absorber.
