Lasers are often portrayed as powerful beams of light that can cut -- even destroy -- missiles, metal, bone, tissue, and, in some sci-fi movies, aliens from outer space. Not all lasers are created ...

Space travel can be agonizingly slow: For example, the New Horizons probe took almost 10 years to reach Pluto. Traveling to Proxima Centauri b, the closest habitable planet to Earth, would require ...

A near-infrared light beam appears harmless, as it is a low-frequency type of light that does not have a dramatic effect but rather passes through tissue unnoticed. However, under some circumstances, ...

A new theoretical study finds shorter laser pulses achieve higher quantum efficiency for photoemission from a solid surface without increasing power or intensity. Using light to knock electrons loose ...

Researchers at Oregon State University have developed and tested in a mouse model a new type of nanoparticle that enables the removal of melanoma tumors with a low-power laser. After the systemically ...

High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, ...

The TECHSPEC broadband, anti-reflection (BBAR) coated right-angle prisms are suitable for use with low-power laser sources for a wide variety of applications. BBAR coating allegedly improves ...

For experiments that require ultra-precise measurements and control over atoms—think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates—lasers are the technology of choice, ...
