A compact fiber-based system has been developed to compress mid-infrared laser pulses to 187 femtoseconds using low input power. By integrating a holmium-doped ZBLAN photonic crystal fiber within a ...

Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical imaging, but their generation often relies on complex ...

Abstract: Air-coupled ultrasonic testing avoids contamination and reduces maintenance costs, but suffers from poor signal-to-noise ratio (SNR) due to impedance mismatch. Rather than developing new ...

Abstract: Quantifying the complexity of biomedical signals offers critical insight into underlying physiological and pathological dynamics. This study systematically evaluates compression-based ...
