Researchers produce laser pulses with record-breaking intensity

Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science in the Republic of Korea. It ...

Rotation of a molecule as an 'internal clock'

Using a new method, physicists at the Heidelberg Max Planck Institute for Nuclear Physics have investigated the ultrafast fragmentation of hydrogen molecules in intense laser fields in detail. They used the rotation of the ...

Plasma guides maintain focus of lasers

In science fiction, firing powerful lasers looks easy—the Death Star can just send destructive power hurtling through space as a tight beam. But in reality, once a powerful laser has been fired, care must be taken to ensure ...

Microscopy images in a flash

Oak Ridge National Laboratory researchers have built a novel microscope that provides a "chemical lens" for viewing biological systems including cell membranes and biofilms. The tool could advance the understanding of complex ...

Saturable plasmonic metasurfaces for laser mode locking

Plasmonic metasurfaces are artificial 2-D sheets of plasmonic unit cells repeated in a subwavelength array, which give rise to unexpected wave properties that do not exist in nature. In the linear regime, their applications ...

Crystal creates a supercontinuum breakthrough

Researchers have generated a wide range of colors from a single laser after discovering a new process for achieving so-called "supercontinuum generation."

Could vacuum physics be revealed by laser-driven microbubbles?

A vacuum is generally thought to be nothing but empty space. But in fact, a vacuum is filled with virtual particle-antiparticle pairs of electrons and positrons that are continuously created and annihilated in unimaginably ...
