A new method of creating laser pulses, more than 1,000 times as powerful as those currently in existence, has been proposed by scientists in the UK and South Korea. The scientists have used computer ...

Conceptually, radar is pretty simple: send out a radio wave and time how long it takes to get back via an echo. However, in practice, there are a number of trade-offs to consider. For example, ...

Solitons are self‐sustaining optical pulses that arise from the precise balance of anomalous dispersion and Kerr nonlinearity in a fibre. Their remarkable stability over long distances underpins ...
