The Texas Petawatt Laser at the University of Texas is the most powerful laser in the world, producing over 1 petawatt of power for a tenth of a trillionth of a second. It is used to replicate extreme conditions and study how matter behaves. The laser can even produce antimatter.
As of January 2009, the most powerful laser in the world is the Texas Petawatt Laser at the University of Texas at Austin in the United States. In March 2008, the laser became the first in the world to cross the 1 petawatt (trillion-billion-watt) mark, an amount of power about 60 times the world’s average energy consumption in 2004, which was about 15 terawatts. The way you get such tremendous power is by activating the laser for only a very short amount of time, just a tenth of a trillionth of a second. Although the total energy produced by the laser is small – about 200 joules, or similar to that burned by a light bulb in a couple of seconds – it is released in such a tiny fraction of time that the power per second (watt) is enormous.
As the most powerful laser on Earth, the Texas Petawatt Laser is being used by scientists to reproduce exotic conditions never seen on Earth, such as the interior, a supernova or the Sun. Laser experiments give scientists a clue as to how it behaves matter under these extreme conditions. Scientists at this laser facility are quick to point out that, for a fraction of a second, it produces “the brightest light in the universe.” The power of the laser briefly eclipses that of the brightest known natural phenomena, gamma-ray bursts, by a factor of more than 100. Naturally, the total power of a gamma-ray burst is much greater than that of the most powerful gamma-ray bursts. mighty of the world. laser, because a burst of gamma rays can be millions of miles long and thousands of miles wide, but based on volume, the laser wins.
The laser’s target is usually a few small clouds of gas in a chamber, which are heated to millions of degrees Celsius and pressurized to a billion times more than sea-level pressure on Earth. Under such conditions, matter is so compressed and energized that little real complexity or order can exist – just atoms packed as close together as possible. The energy of the world’s most powerful laser is so intense that it can cross the threshold necessary for the spontaneous production of antimatter. Antimatter, the reflection of conventional matter, spontaneously converts to energy upon contact with normal matter in a process known as annihilation. Annihilation can only be observed in test chambers due to the unique particles released from the process.
