This study is led by professor Tianrui Zhai (Faculty of Science, Beijing University of Technology). The fiber braiding cavity is designed to achieve the red-green-blue (RGB) whispering gallery mode ...

Helium-neon lasers may be little more than glorified neon signs, but there’s just something about that glowing glass tube that makes the whole process of stimulated emission easier to understand. But ...

In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade.

The team's experimental setup: Atoms are cooled and slowed inside a vacuum chamber, until they can be trapped in a lattice inside a cavity (black triangular cavity spacer in the bottom half of the ...

Colloidal quantum-dots (CQDs) have emerged as promising gain media for lasers, offering low lasing thresholds, compatibility with low-cost solution-based synthesis and processing methods, and tunable ...
