Isolator-free unidirectional thulium-doped fiber laser [PDF]
Light: Science & Applications, 2015 We report the first demonstration of a unidirectional, isolator-free 2-mmthulium-doped fiber (TDF) laser, relying on the properties of the theta cavity (ring resonator with S-shaped feedback). The core pumped theta cavity TDF laser provides sub-Watt output power with a slope efficiency of 25%, a 2 dB flat tuning range of 1900–2050 nm, and a linewidth ...

Quasi‐Single‐Mode Polaritonic Crystal for Hyperbolic Phonon‐Polaritons
Advanced Optical Materials, EarlyView.Near‐field study of the polaritonic Fourier crystal with α‐MoO3 reveals that the hyperbolic phonon‐polaritons within the Type‐I Reststrahlen band may form a quasi‐single‐mode Bloch wave where only the fundamental mode propagates in the crystal. Our results demonstrate the realization of a quasi‐single‐mode regime for the inherently multimode hyperbolic

Advanced Optical Materials, EarlyView.Goos‐Hänchen shift (GHS) is a phenomenon in which an optical beam experiences a longitudinal displacement upon total internal reflection. In this work, we experimentally demonstrate an enhanced GHS in the wavelength domain using a helical fiber grating (HFG).

Cricopharyngeal myotomy with thulium laser through flexible endoscopy: proof-of-concept study
Endoscopy International Open, 2018 Background and study aims Endoscopic treatment of Zenker’s diverticulum has proven feasible, but electrocautery and CO2 laser technology carry the risk of collateral thermal injury. Thulium laser septum incision may overcome this limitation.
