Researchers have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. They demonstrate that an approach for generating terahertz waves using intense laser pulses in air can be done with much lower power lasers, a major challenge until now. They have exploited the underlying physics to reduce the necessary laser power for plasma generation.
