Active mode-locking via pump modulation in a Tm-doped fiber laser

APL Photonics, 2016
We propose and experimentally realize a new class of actively mode-locking technique using pump modulation for rare-earth doped fiber lasers. A Tm-doped fiber laser at 2 μm is mode-locked using the proposed active mode-locking via pump modulation ...

Tapered-EDF-Based Mach–Zehnder Interferometer for Dual-Wavelength Fiber Laser

IEEE Photonics Journal, 2014
An all-fiber comb filter using a tapered-erbium-doped fiber in a Mach-Zehnder interferometer structure is presented. The free spectral range, extinction ratio, bandwidth, and interference pattern of the comb filter can be shaped by controlling the taper ...

Simultaneous ToF/FMCW LiDAR Using a Dual‐Mode Light Source in a Single Architecture

Laser &Photonics Reviews, EarlyView.
A simultaneous ToF/FMCW LiDAR architecture is demonstrated using a dual‐mode light source that alternately generates optical pulses and frequency‐chirped light within a single acquisition. By combining time‐domain ToF and coherent FMCW ranging, the system achieves high‐resolution ranging and velocity sensing while extending the measurable range beyond ...

Repositioning Non‐Ablative Fractional Lasers ‐ Molecular and Histological Insights from a scoping review

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Near‐infrared non‐ablative fractional lasers (NAFL) are established for skin rejuvenation and scar treatment and have attracted interest for their expanding therapeutic potential. This scoping review aims to revisit and reposition NAFL within a fluence‐dependent continuum of tissue modulation, based on evidence from 27 studies of lasers ...

High power cladding-pumped Raman fiber laser with true single-mode output at 1660 nm

, 2006
We report a 10 W continuous-wave cladding-pump Raman fiber laser with single-mode output at 1660 nm pumped by a high-power Er:Yb fiber amplifier. The laser threshold was 6.5 W and its slope efficiency was 67%

Root surface biomodification in periodontal therapy: Biological rationale and clinical applications

Periodontology 2000, EarlyView.
Abstract Regenerative periodontal therapy aims to form new cementum, periodontal ligament, and alveolar bone, all sealed by gingival tissue. The root surface acts as the wound margin during this regeneration process. Root surface biomodification (root conditioning/root decontamination), therefore, seems instrumental in promoting surface decontamination

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.
