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 ...

The Journal of Physiology, EarlyView.Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

The Journal of Pathology, Volume 270, Issue 2, Page 139-162, October 2026.Abstract Prostate cancer (PCa) is the second most common type of neoplasm, currently treated with a variety of therapeutic agents. Although advances in treatment over the past decade have improved overall survival, patients with advanced PCa eventually progress from hormone‐sensitive PCa to metastatic castration‐resistant PCa.

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%

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.Abstract The hypothalamic–pituitary–gonadal (HPG) axis coordinates reproductive function and incorporates gonadal sex steroid feedback to regulate gonadotropin secretion in a homeostatic manner. In females, ovarian estrogens and progestins act as the primary negative feedback signals to suppress luteinizing hormone (LH) release, whereas in males ...

Polarization‐Controlled Wavelength‐Tunable Pulsed Laser Based on Metafiber
Nanophotonics, Volume 15, Issue 17, 11 September 2026.A polarization‐sensitive Au‐nanorod metasurface has been proposed that integrates saturable absorption with wavelength‐tuning capabilities. By fabricating this metasurface structure on the facet of the fiber, known as a metafiber, low‐loss coupling between the metasurface and the fiber laser system is achieved.
