If the detuning is changed from blue to red by adjusting the atom–cavity detuning while keeping the dipole power constant and the probe laser resonant with the cavity, the average storage time ...

Physicists in Germany have developed a new technique to cool atoms with lasers. The method is applied to single atoms trapped in an optical cavity and is five times faster than conventional laser ...

The length of this resonant cavity is crucial for controlling the target laser wavelength, called the resonance wavelength. Thus far, two types of GaN-based VCSEL structures have been developed ...

Lasers work by making energetic particles ... of high-energy ammonia molecules and a hollow enclosure called a resonance cavity to force microwaves to oscillate together. However, its power ...

Helium-neon lasers may be little more than glorified ... opposite the Brewster window and aligned to create a resonant optical cavity external to the tube. To switch mirrors easily, [Les] crafted ...

The continuous-wave laser is one of the key achievements of the fundamentals, functionalities and applications of cavity solitons (FUNFACS) project. The team hopes to develop a pulsed laser by the end ...

Metasurface enters laser fiber cavity for spatiotemporal mode control: Yang and co-authors provide a brief explanatory video. Credit: Advanced Photonics (2023). DOI: 10.1117/1.AP.5.2.026002 As ...

Light enters the cavity through one of the mirrors and bounces back and forth multiple times, creating standing waves at resonant wavelengths. Fabry-Pérot cavities are widely used in lasers, optical ...

As no light excitation is needed, the approach in principle circumvents the problems associated with continuous laser driving. This is the first work demonstrating such cavity control over ...

In just seconds, the newest dental lasers can alter the chemical composition of teeth enamel, making it stronger. Even more revolutionary may be their ability to prevent cavities before they start.
