Application of a three-lens slit spatial filter in high power lasers - ScienceDirect
Laser Focus World - Plasma-lens filter improves temporal contrast of ultrafast laser pulses; a plasma-lens filter (STPLF) passes the highest-intensity temporal pulse portions and scatters the lower-intensity prepulse while providing spatial filtering --
