Fiber Raman Amplifiers and Fiber Raman Lasers [PDF]

Micromachines, 2020
Stimulated Raman scattering (SRS) is a nonlinear optical effect, observed for the first time in 1962, which lies at the heart of fiber Raman amplifiers and fiber Raman lasers [...]

Random Fiber Laser

Physical Review Letters, 2007
We investigate the effects of two dimensional confinement on the lasing properties of a classical random laser system operating in the incoherent feedback (diffusive) regime. A suspension of 250nm rutile (TiO2) particles in a Rhodamine 6G solution was inserted into the hollow core of a photonic crystal fiber (PCF) generating the first random fiber ...

Real-time multispeckle spectral-temporal measurement unveils the complexity of spatiotemporal solitons

Nature Communications, 2021
Observing 3D dissipative solitons is very challenging since their formation is stochastically and not repeatable. Here, the authors report the real-time multispeckle spectral-temporal observation of dissipative solitons in an optical fiber and analyze ...

Fiber Lasers [PDF]

Laser Technik Journal, 2014
AbstractFiber lasers have already firmly established themselves within the industrial production sector and are synonymous with efficiency, precision and cost‐effectiveness in a large number of laser material processing applications. They offer excellent single‐mode or multi‐mode beam qualities, which can be precisely adapted to the processing task and

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Spectrum-tailored random fiber laser towards ICF laser facility

Matter and Radiation at Extremes, 2023
Broadband low-coherence light is considered to be an effective way to suppress laser plasma instability. Recent studies have demonstrated the ability of low-coherence laser facilities to reduce back-scattering during beam–target coupling.
