Optimal laser focusing for positron production in laser–electron scattering
Laser–electron beam collisions that aim to generate electron–positron pairs require laser intensities I ≳ 10 ^21 W cm ^−2 , which can be obtained by focusing a 1-PW optical laser to a spot smaller than 10 μ m. Spatial synchronization is a challenge because of the Poynting instability that can be a c...
