MARS: Programmable multipurpose auto‐release system for aquatic observations

Limnology and Oceanography: Methods, EarlyView.
Abstract Aquatic biodiversity assessments are often labor‐intensive due to the large size of the equipment and the complex logistics of sea vessel operations. Traditional drift and drop cameras are typically tethered to the surface, causing cable and line clutter on sea vessels.

Deconvolution Techniques in Optical Coherence Tomography: Advancements, Challenges, and Future Prospects

Laser &Photonics Reviews, EarlyView.
This review explores deconvolution techniques in optical coherence tomography (OCT), addressing resolution degradation from point‐spread functions (PSF). It reviews foundational principles (e.g., Richardson‐Lucy deconvolution) to advanced AI‐driven methods, emphasizing clinical translation and interdisciplinary collaboration. Real‐world implementations

Temperature‐Dependent Spectroscopy and Laser Performance of Yellow Tb:YLF Lasers with 36% Slope Efficiency at Room Temperature and 61% at 100 K

Laser &Photonics Reviews, EarlyView.
Highly efficient cryogenic yellow laser performance of Tb:YLF (Tb3+:LiYF4) is reported. The room temperature slope efficiency of 36% increases to 61% at 100 K, while the wavelength changes from 587 to 581 nm. Moreover, red laser emission at 624 nm with 47% slope efficiency at 78 K is demonstrated.
