Phys.org / Why ultrashort laser pulses could make low-power electron sources far more practical

A new theoretical study finds shorter laser pulses achieve higher quantum efficiency for photoemission from a solid surface without increasing power or intensity. Using light to knock electrons loose from a surface—known ...
