Today, a breakthrough in laser pulse compression technology has been announced by researchers at the University of Oxford. By combining a density gradient with laser pulse compression, they have developed a way to compress high-intensity laser pulses to much shorter duration while maintaining their peak power. This new technique could have far-reaching implications for lasers used in applications such as ultrafast spectroscopy and strong-field physics. The team has demonstrated that the peak power of a laser pulse can be increased by a factor of 5 compared to conventional laser pulse compression techniques. This could lead to a new generation of lasers with higher power and shorter pulse duration, allowing researchers to explore new areas of science and technology.
