Application of Thulium Fiber Laser in Plastic Surgery

Cosmetics
We present our experience of using the UROLASE+ surgical system, based on thulium laser technology, in the context of plastic surgery. Our work with the thulium fiber laser for soft tissue dissection in vitro, ex vivo, and in vivo is described, and the ...

Emission Wavelength Limits of a Continuous-Wave Thulium-Doped Fiber Laser Source Operating at 1.94 µm, 2.09 µm or 2.12 µm

Photonics
We present a thulium-doped single-oscillator monolithic fiber laser emitting successively at three wavelengths, especially at unusual long wavelengths as 2.09 µm and even at 2.12 µm.

Tunable 30W all-fiber laser emitting around 1850 nm [PDF]

EPJ Web of Conferences
We have demonstrated a tunable polarization maintaining thulium-doped fiber laser spanning the 1830nm-1880nm range with a fiber-coupled output power as high as 30W CW. The high- power booster stage is made using double clad fibers pumped with 793nm laser

152 fs nanotube-mode-locked thulium-doped all-fiber laser. [PDF]

, 2016
Ultrafast fiber lasers with broad bandwidth and short pulse duration have a variety of applications, such as ultrafast time-resolved spectroscopy and supercontinuum generation. We report a simple and compact all-fiber thulium-doped femtosecond laser mode-

Comparative assessment of structural changes in the prostate after bipolar plasma and thulium fiber laser enucleation of benign prostatic hyperplasia

Acta Biomedica Scientifica
Background. Benign prostatic hyperplasia (BPH) is a common disease in older men. Transurethral surgery in BPH is the gold standard for treatment, but the techniques differ in the energy used.

A Multi-Wavelength Thulium-Doped Fiber Laser Using a Photonic Crystal Fiber-Based Sagnac Loop

IEEE Photonics Journal, 2022
A multi-wavelength thulium-doped fiber laser incorporating a photonic crystal fiber (PCF) Sagnac loop was presented and experimentally demonstrated. In the laser cavity, the Sagnac loop mirror used a 0.5 m PCF as a comb filter.

Simulation of Optical Fiber Amplifier Gain Using Equivalent Short Fibers

, 2019
Electromagnetic wave propagation in optical fiber amplifiers obeys Maxwell equations. Using coupled mode theory, the full Maxwell system within an optical fiber amplifier is reduced to a simpler model.

A Vascular Microphysiological Model of Lung Fibrosis Reveals That Myofibroblasts and IPF Patient‐Derived Fibroblasts Impair Angiogenesis and Vasculogenesis

Advanced Functional Materials, EarlyView.
A microphysiological lung fibrosis model recapitulates myofibroblast–vascular interactions. Induced myofibroblasts and patient‐derived IPF fibroblasts impair angiogenesis and increase vascular permeability via TGF‐β1–driven signaling. Pharmacological interventions with SB 431542 and VEGF supplementation restore vascular morphology and barrier function.
