How long quantum tunneling takes to happen?

The difficulty in answering this question lies in the definition of time itself.

New research sets record for shortest laser pulse

The project creates a more powerful, versatile ultrafast laser pulse.

Scientists achieved world record-high data transmission over 75 km

Using a significant class of micro-comb called soliton crystals, scientists achieved ultra-high data transmission over 75 km of standard optical fiber using a single integrated...

Accelerating long-range coherent LiDAR by using photonic circuits

Lidar, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to...

Generating strong magnetic fields rapidly using laser pulses

Magnetic fields are inseparable from light-matter interaction. They play a vital role in multiple research areas, such as medicine. But, generating strong magnetic fields...

Scientists created a wide range of colors from a single laser

Supercontinuum generation is when intense laser light of one color travels within a material, similar to glass, and expands into a spectrum of colors....

A miniature double particle accelerator to recycle some of the laser energy

Using a longer pulse comprising many cycles of terahertz waves, DESY scientists have devised a tiny double particle accelerator that can recycle some of...

Capturing a picture of a light pulse

The advance will now help to clarify important details about the interaction of light and matter.

Generating first laser ultrasound images of humans

Technique may help remotely image and assess health of infants, burn victims, and accident survivors in hard-to-reach places.

Cytophone detects cancer in earlier stages and prevents fatal disease spread

A team of scientists at the University of Arkansas for Medical Sciences (UAMS) has successfully tested a non-invasive device called "Cytophone" that can detect...

Researchers can boost the properties of electronics by shooting them with laser

Researchers at Northeastern have taken the first step in developing the next generation of electronics. They are developing a new way to change the...

New electro-optic laser pulses 100 times faster than usual ultrafast light

Using common electronics, NIST scientists have developed a laser that pulses 100 times more often than conventional ultrafast lasers. This newly developed laser is expected...
