peta- +‎ watt.

Examples

  • Livermore researchers detected anti-matter about 10 years ago in experiments on the since-decommissioned Nova "petawatt" laser - about 100 particles.

  • A petawatt is 1,000 terawatts Anxiety grows over use of nuclear energy, 24 March, page 29.

    Corrections and clarifications

  • "But when we ran computer simulations using these next generation petawatt (quadrillion watt) strength lasers with a hydrogen-boron fuel, we were shocked to find that it's only 10 times more difficult than deuterium-tritium," he said.

  • A petawatt is 1,000 times more power than that, and an exawatt is 1,000 times greater than a petawatt.

  • However, with wavelengths of only 13 nanometers and high radiation intensities of several petawatt per square centimeter something else - at least with some atoms - happens: With xenon, a whole light-wave packet immediately seems to knock out a huge number of internal electrons.

  • Such high energies and short pulse durations allow significant laser powers to be produced with laser-pulse energy approaching the petawatt level - or up to a quadrillion watts.

  • These experiments represent a four-fold increase in the on-target laser energy compared to any previous petawatt-class laser system.

  • They calculate that this means a global energy demand of just 100 petawatt-hours annually, as opposed to say 150.

    The Register

  • The pulses of light can reach 1 quadrillion watts (a petawatt) but last just one-tenth of a trillionth of a second.

  • They mentioned the previous petawatt laser experiment that was decommissioned, but I didn't see where it mentioend the power required for this experiment.
