Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass ...

"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.

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 ...

Researchers at the University of California, Los Angeles (UCLA) have unveiled a new optical technology that enables precise ...

Much of our waste is far too valuable to simply be incinerated. If it is recycled in a carefully controlled way, not only can ...

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 ...

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 Heterodyne Spectroscopy Group in the Department of Terahertz and Laser Spectroscopy works on the development of instruments and methods for high-resolution THz spectroscopy based on mm-wave ...

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 ...

She was one of the first researchers to demonstrate impact ionization in electronic materials using a terahertz free electron laser. More recently, her team developed accessible techniques that use ...

Biomass can be converted into valuable gases. But in order to control this process, the amount of water vapor has to be measured. This is notoriously hard, because other components of the gas can ...
