Early observations of 'critical self-focusing' of laser pulses date back to the mid-1960s. This effect manifests itself as an explosive growth in the laser intensity combined with a severe narrowing of the "waist" of the laser pulses. Now physicists have created for the first time a set of self-focused femtosecond light channels, which could have wide-ranging applications.
