Nearly 60 Years in the Making โ€“ Todayโ€s High Power Lasers

This article marked the 50th anniversary of development of the laser in 1960 and details the development path from that first few hundred watt laser to todayโ€s ultrapowerful petawatt and exawatt laser systems. The invention of the laser nearly 60 years ago has led to the latest generation of devices, with power bursts thousands of

Laser-Heated Nanowires Produce Micro-Scale Nuclear Fusion With Record Efficiency

Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. Itโ€™s also happening โ€“ at a smaller scale โ€“ in a Colorado State University laboratory. Using a compact but powerful laser to heat arrays of ordered nanowires, CSU scientists and collaborators have demonstrated micro-scale nuclear fusion in
