Scientists developed a technique to amplify laser power a millionfold, using plasma's density gradient to combine photons and boost intensity.
In November 2023, we reported that scientists from the UK and South Korea had developed a new technique to amplify laser power by theoretically using plasma a million times. By exploiting plasma’s density gradient, they found that combining photons significantly increased laser intensity.
The potential to increase laser power by such a massive amount has far-reaching implications. The most powerful lasers in the world have a peak power of around ten petawatts. Ramping up laser power by orders of magnitude approaching or exceeding a million times would help in this field of study. Professor Dino Jaroszynski from the University of Strathclyde’s Department of Physics believes that these advancements will enable the development of next-generation laser-plasma accelerators, which are significantly smaller than conventional accelerators.
Light can induce unique and extreme conditions that are not normally observed under standard experimental setups at these high intensities.This includes the ability to generate new states of matter, explore the fundamental properties of the vacuum, and simulate astrophysical phenomena such as those occurring in the interiors of stars.
The collaborative efforts of the UK and South Korean teams will soon be put to the test in laboratory settings, aiming to validate their theoretical models through experimental evidence.
