Elad Harel is used to shining a light on the mysteries of the natural world. Working at the cutting-edge of ultrafast ...

Terahertz radiation (THz), electromagnetic radiation with frequencies ranging from 0.1 and 10 THz, is central to the ...

A novel method transforms common liquids into epsilon-near-zero materials using femtosecond laser pulses, enabling unique ...

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

Thin-disk single-cavity dual-comb lasers (TDSCs) offer a promising alternative to traditional dual-comb systems, simplifying ...

Then, when hit with a terahertz laser, the atoms are stimulated to the same frequency as the material’s collective vibration, or “phonons.” This nudges FePS 3 out of its antiferromagnetic balance and ...

By applying intense pulses of terahertz-frequency light to this material, they were able to control this transition, placing the material in a metastable magnetic state that lasts for more than 2.5 ...

Jan. 30, 2025 — Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot ... Optical Fiber Sensor ...

Abstract: We propose and experimentally demonstrate a terahertz (THz) source based on optical rectification in lithium niobate wafers driven by an ultrafast ytterbium laser. Terahertz pulses with a ...

The new TrueLase PM 30/400 gain fiber is designed for single frequency lasers and pulsed applications requiring high pulse energy and kW average power. It offers simple splicing, high polarization ...
