The winter months, when people spend significantly less time in the sun, are typically known as “laser season” by skin experts—if you’re considering a treatment, now is a great time. “We perform laser ...

Accelerometers turn motion into measurable signals. From tilt and vibration to g-forces, they underpin countless designs. In this “Fun with Fundamentals” entry, we demystify their operation and take a ...

In the present study, the theoretical framework underlying interferometric measurement using multimode lasers—forming the basis of laser vibrometry—is comprehensively described. A numerical simulation ...

At-home laser hair removal devices have been popular for their convenience, safety, relative comfort and results. If you’re curious about trying one out yourself, you may be wondering if the portable ...

Abstract: We demonstrate an improved Fabry-Pérot interferometer (FPI) fiber accelerometer using ultra-short fiber Bragg gratings (FBGs) fabricated with femtosecond laser Plane-by-Plane direct-writing.

Quantum accelerometers are advanced motion sensing devices that utilize the principles of quantum mechanics to achieve extraordinary levels of sensitivity and precision. Unlike traditional ...

The age of the laser weapon is finally upon us. The United States Army has officially sent a pair of high-energy laser weapons overseas to defend American troops and US allies against enemy drones, ...

The demand for microelectromechanical systems (MEMS) resilient to harsh environments is growing. Silicon-based MEMS struggle under extreme conditions, limited by their performance at elevated ...

There may not be a fountain of youth, but laser treatments may be the next best thing. The category has seen its fair share of advancements and innovation over the last few decades. Now, there are ...
