Optical-based sensing approaches have long been an indispensable way to detect
molecules in biological tissues for various biomedical research and applications. The …

Fiber laser technology has experienced a rapid growth over the past decade owing to
increased applications in precision measurement and optical testing, medical care, and …

Here, we report an all-fiber tunable ultrafast Raman laser synchronously pumped by a home-
made 1.6 µm dissipative soliton (DS) picosecond (ps) laser, which produces Stokes light …

Lipid imaging by conventional photoacoustic microscopy subjects to direct contact sensing
with relatively low detection bandwidth and sensitivity, which induces superficial imaging …

Photoacoustic imaging (PAI), also known as optoacoustic imaging, is a hybrid imaging
modality that combines the rich contrast of optical imaging with the deep penetration of …

We present a wavelength‐switchable, synchronously pumped Raman fiber laser based on a
dual‐cavity design operating in the 1.7 µm region, specifically developed for multispectral …

Atherosclerosis is a major cause of mortality and morbidity, and rupture can lead to
myocardial infarction and stroke. The vulnerability assessment of atherosclerosis plaques is …

A hundred-watt-level spatial mode switchable all-fiber laser is demonstrated based on a
master oscillator power amplifier scheme. The performance of the amplifier with two seed …

Photoacoustic molecular imaging technology has a wide range of applications in biomedical
research. In practical scenarios, both the probes and blood generate signals, resulting in the …

Here, we report a passively Q-switched Tm laser at 1720 nm. The Q-switching behavior
originates from a piece of Tm-doped fiber. Tm-doped fiber has a broad absorption spectrum …
