From unconventional laser beams to a more robust imaging wave

Researchers have come up with a way to use an unconventional laser beam — called an Airy beam — to create terahertz (THz) waves. THz waves can yield high-resolution images of hidden objects and are not considered harmful to human tissue, making them highly attractive for law enforcement and medical purposes. The THz waves created in Rochester are 5.3 times stronger than those generated by move conventional means.
