Concentrating light into such a small volume increases the strength of light–matter interactions, and can alter the spontaneous emission from a light source inside the cavity. Cavities can be ...

Peritoneal washing (abdominopelvic washing) is a procedure used to diagnose whether certain types of cancer are present in the peritoneal cavity—the space between the membranes that line the abdomen.

High bandwidth can be supported using OM3, a multimode fiber optic cable with a 50-micron glass core and an 850 nm vertical-cavity surface-emitting laser (VCSEL) light source. Other benefits of this ...

To be precise, their goal was to create a femtosecond laser cavity using carefully aligned optics. Rather than using the traditional, discrete method, they used a commercial femtosecond laser to ...

Each cavity is driven by a high-power klystron, which is a tube containing electron beams. The electron beams are intensity-modulated to a frequency of 400 MHz, or 400 million oscillations per second.
