Liquids take a shine to terahertz radiation


In a significant breakthrough, scientists at the Ultrashort Pulse High Intensity Laser Laboratory (UPHILL) of this Institute have devised a high power radiation source in the much sought after terahertz (THz) region of the electromagnetic spectrum. This study, done in collaboration with laboratories in Greece and France, appeared in the journal Nature Communications on Oct 30, 2017. The search for new and brighter radiation sources is an enduring quest in science and technology [1,2]. While there are many sources across the entire electromagnetic spectrum, the terahertz region (wedged between the infrared/optical and the microwave regions) has been a challenge and it is only in the last twenty years that sources have started becoming available.
