When researchers at the Galatea laboratory in Switzerland set out to create a femtosecond laser in glass they weren’t certain it was going to work. To be precise, their goal was to create a ...

Lasers are pretty much magic — it’s all done with mirrors. Not every laser, of course, but in the 1980s, the most common lasers in commercial applications were probably the helium-neon laser, which ...

Researchers have shown that high-dispersion mirrors can replace prisms and gratings to produce efficient laser output from a compact source. Ti:sapphire femtosecond lasers currently use optical ...
