In laser-plasma based particle accelerators, a second laser pulse colliding with the first is used to obtain better control over the injection and subsequent acceleration of electrons. In this scheme, the electron beams are highly collimated, monoenergetic (with energy spread < 10%), tuneable (between 15 and 250 MeV) and most importantly, stable.
