How to make lasers simple or chaotic

New forms of highly efficient laser could be in the pipeline as a result of research that brings new detailed understanding of fundamental laser processes. Professor Nail Akhmediev and his international collaborators modelled the interaction of high-powered...

Internal rogue wave could have sunk Indonesian submarine

The sinking of an Indonesia submarine in April this year may have been caused by a wave up to 100 metres high, travelling within the ocean. Internal waves occur at sharp boundaries in the ocean along interfaces between layers of differing densities,...

Lasers replicate extreme weather events

Studies in the laboratory involving pulsing lasers could lead to a warning system that will alert ships to the imminent approach of a devastating freak wave. The research led by Professor Nail Akhmediev from the Australian National University's Research...

Lego pirate proves, survives, super rogue wave

Scientists have used a Lego pirate floating in a fish tank to demonstrate for the first time that so-called ‘super rogue waves’ can come from nowhere in apparently calm seas and engulf ships. The research team, led by Professor Nail Akhmediev...
