The heat is on for the world's biggest laser
The National Ignition Facility in the Us is pursuing one of the grand challenges of science: controlled thermonuclear fusion in the laboratory. Our American correspondent Breck Hitz talks big science with Edward Moses, the director of NIF's multibillion-dollar research programme.
Picosecond lasers: the power of cold ablation
Picosecond lasers are a universal tool for ablating almost any material without the downsides of unwanted thermal side-effects. Bernhard Klimt and colleagues at LUMERA LASER explain how cold ablation has changed the face of micromachining.
Marking the laser's 50-year journey from the first flash of coherent light, Thomas Baer tells OLE why it's time to celebrate one of the great inventions of the modern age.
