This cosmic paperweight is handmade by an artist who uses laser beams to make tiny stars: Each laser pulse passes through the glass except at its focal point, where the concentrated energy creates a bright star.

Now, US physicists have helped to break that mould by creating the first curved laser beams.

The information in a holographic crystal is recorded by an interference pattern — regions of varying brightness and darkness — created by two laser beams of the same wavelength but varying in phase.

The discovery came while British chemist Harold Kroto was visiting the Rice University lab of American chemist Richard Smalley; they were trying to create new forms of carbon that might exist in interstellar space by bombarding graphite with a laser beam.

Owing to such quantum beams with large current, we can make a big step forward not only for creating new fundamental technologies such as medical applications and non-destructive inspection of social infrastructures to contribute to our future life of longevity, safety, and security, but also for realization of laser fusion energy triggered by fast ignition.

The global maps were created from data obtained by an instrument called the Mars Orbiter Laser Altimeter (MOLA), which bounces an infrared laser beam off the surface and calculates the distance from the spacecraft by measuring the time it takes to detect the reflected pLaser Altimeter (MOLA), which bounces an infrared laser beam off the surface and calculates the distance from the spacecraft by measuring the time it takes to detect the reflected plaser beam off the surface and calculates the distance from the spacecraft by measuring the time it takes to detect the reflected pulse.

Inertial confinement fusion (ICF) seeks to create those conditions by taking a tiny capsule of fusion fuel (typically a mixture of the hydrogen isotopes deuterium and tritium) and crushing it at high speed using some form of «driver,» such as lasers, particle beams, or magnetic pulses.

By delicately weaving 1500 layers together, a team of researchers created a «quantum cascade» that amplified this effect into a laser beam.

The high temperatures at the interior of the Earth were created by heating samples with a laser beam.

The atoms are chilled to temperatures near absolute zero and levitated in a vacuum by an optical lattice, a «crystal of light» created by intersecting external laser beams.

When co-author Zhaoming Zhu, Gauthier's postdoctoral research associate, encoded information onto one of these beams, the data could be imprinted on these newly created phonons and retained for 12 billionths of a second, long enough to be transferred back to light again by shining a third laser through the fiber.

Once created, each entangled pair of photons is separated by passing a laser beam made up of them through a filter made from a non-linear crystal.

The experiment, developed by physicists from The Australian National University (ANU) and UNSW ADFA, created an extremely cold gas trapped in a laser beam, known as a Bose - Einstein condensate, replicating the experiment that won the 2001 Nobel Prize.

According to the theory developed by the researchers in this study, the laser beam creates a high - energy molecular excitation, yet in order to do so it must absorb heat from the low - energy metallic component, which thus cools.

For example, he showed how it was possible to greatly increase the effective length of the interferometer arms by creating what is known as a Fabry - Pérot cavity, in which the laser beams bounce back and forth many times between mirrors at either ends of the arms before their recombination at the beam splitter.

The light is created through the conversion of the beams emitted by tiny laser diodes by means of a fluorescent phosphor material inside the headlight.
