petawatt lasers

Petawatt lasers are extremely powerful laser systems capable of delivering a trillion (10^15) watts of power in a very brief pulse, typically lasting a few femtoseconds to picoseconds. They generate immense energy focused into tiny spots, creating conditions similar to those inside stars or nuclear explosions. These lasers are used in cutting-edge research, such as exploring nuclear fusion, studying material properties under extreme conditions, and advancing particle acceleration techniques. Despite their immense power, the energy is concentrated in ultrashort bursts, making them valuable tools for scientific discovery without destructive effects on their surroundings.
