Research team presents novel transmitter for terahertz waves

Terahertz waves are becoming ever more important in science and technology. They enable us to unravel the properties of future materials, test the quality of automotive paint and screen envelopes. But generating these waves ...

Few-cycle pulses break the 300 W barrier

A team led by researchers from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), Laser-Laboratorium Göttingen (LLG) and Active Fiber Systems (AFS) has generated multi-millijoule 3-cycle pulses ...

Fluc­tu­a­tions in the void

In quantum physics, a vacuum is not empty, but rather steeped in tiny fluctuations of the electromagnetic field. Until recently it was impossible to study those vacuum fluctuations directly. Researchers at ETH Zurich have ...

Extreme light

Across six decades, scientists and engineers have transformed the briefest flash of laser light into ultrafast pulses that pack a powerful punch. Rebecca Pool from ESCI talks to Nobel Laureate, Professor Gerard Mourou, to ...

What really happens at femtosecond junctions?

When beams of ultra-short laser pulses running in the same direction intersect with each other at a noticeable angle, various interactions occur between the pulses. These physical phenomena are complicated, and their mathematical ...
