Research team demonstrates fractal light from lasers
Fractal patterns are common in nature, including in the geometric patterns of a tortoise shell, the structure of a snail shell, the leaves of a succulent plant that repeat to create an intricate pattern, and the frost pattern on a car's windshield in winter.

'Quiet' light
Spectrally pure lasers lie at the heart of precision high-end scientific and commercial applications, thanks to their ability to produce near-perfect single-color light. A laser's capacity to do so is measured in terms of its linewidth, or coherence, which is the ability to emit a constant frequency over a certain period of time before that frequency changes.

New phenomenon discovered that fixes a common problem in lasers: Wavelength splitting
A team led by University of Utah physicists has discovered how to fix a major problem that occurs in lasers made from a new type of material called quantum dots. The never-before-seen phenomenon will be important for an emerging field of photonics research, including one day making micro-chips that code information using light instead of electrons.

Researchers discover anti-laser masquerading as perfect absorber
Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of "time-reversed laser" known as a coherent perfect absorber (CPA).

Radioactive material detected remotely using laser-induced electron avalanche breakdown
Physicists at the University of Maryland have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the material, the new technique is able to detect shielded material from a distance. The method improves upon current technologies that require close proximity to the radioactive material.
