"My group has been working on the generation of THz radiation by laser-induced filaments in air for almost 20 years," Aurélien Houard, senior author of the paper, told Phys.org.

Recent advancements in terahertz sensing technology show promise for non-invasive skin cancer detection, improving early ...

This involves shining a laser or other high-power light source onto a photoconductive material, which creates a fast electrical pulse. When this pulse passes through a resonant cavity, it generates ...

This new research builds on Razeghi group’s many years of research with Northwestern’s Center for Quantum Devices, including the development of the first single mode room temperature terahertz laser ...

Impact and Future Applications This advancement is particularly valuable for high-energy THz sources, such as those generated by large-scale laser facilities, which produce low-repetition-rate ...

Scientists have unlocked a way to read magnetic orientation at record-breaking speeds using terahertz radiation. Modern hard ...

Researchers have now demonstrated this effect using single-cycle terahertz pulses — instead of optical pulses — in a variety of liquids. In a laser system, the Kerr effect can be used to ...

The department of Terahertz and Laser Spectroscopy (TLS) has a long track record in instrumentation development for and application of laser-based spectroscopic techniques ranging from the Ultraviolet ...
