Spectral-focusing CARS spectroscopy driven by an all-PM-fiber gain-managed nonlinear amplifier
We demonstrate a spectral-focusing coherent anti-Stokes Raman scattering (SF-CARS) spectroscopy system driven by a single all-fiber gain-managed nonlinear amplification laser. By exploiting the synerg...
Epitaxial layer to boost betavoltaic performance in SiC Schottky diodes
Betavoltaic cells harness the decay of beta-radiation to directly generate electrical power—making them of interest for powering remote or isolated devices. Compound semiconductors are promising mater...
High-resolution compact computational spectrometer using enhanced mode interference in a chaotic multimode fiber
The development of high-resolution, miniaturized, and cost-effective spectrometers remains a critical technical challenge. In this work, we demonstrate a high-resolution computational spectrometer by...
Ultrafast probing of heterostructure dependent coherent acoustic phonon decoherence in AlGaN/GaN HEMT heterostructures
We investigate the influence of heterostructure engineering on the generation, propagation, and decoherence of coherent acoustic phonons (CAPs) in GaN-based materials using ultrafast pump–probe transi...
Fully automated electrodeposition of perovskite thin films for efficient solar cells
Electrodeposition technology has shown unique application potential in perovskite solar cell fabrication due to its characteristics of requiring only water and alcohol solvents without the need for hi...
Compact, efficient, low-threshold 320 nm continuous-wave ultraviolet laser
This paper reports a compact, efficient, low-threshold continuous-wave 320 nm ultraviolet laser based on a linear cavity with Pr:YLF and LiB3O5 (LBO) crystals. Thermal effects were analyzed via a thre...
