In a paper that made the cover of the journal Applied Physics Letters, an international team of researchers has demonstrated an innovative technique for increasing the intensity of lasers.

Researchers Jean-Claude Kieffer of the Institut national de la recherche scientifique (INRS), E. A.

Khazanov of the Institute of Applied Physics of the Russian Academy of Sciences and in France Gérard Mourou, Professor Emeritus of the Ecole Polytechnique, who was awarded the Nobel Prize in Physics in 2018, have chosen another direction to achieve a power of around 10^23 Watts (W).

INRS Professor Jean-Claude Kieffer is regarded as a leader in Canada and is internationally known in the field of science and ultra rapid laser technology.

The particular behaviour of the wave inside this solid medium broadens the spectrum and allows for a shorter pulse when it is recompressed at the exit of the plate,” explains Jean-Claude Kieffer, co-author of the study published online on June 15, 2020, in the journal Applied Physics Letters.

The paper “Thin plate compression of a sub-petawatt Ti:Sa laser pulses” made the cover of the journal Applied Physics Letters, Volume 116, Issue 24 published June 15, 2020.

“We would be among the first in the world to achieve this level of power with a laser that has such short pulses,” says Professor Kieffer.

This is an extremely interesting direction that has the potential to take the scientific community to new horizons,” says Professor Kieffer.
