Key Details
Proposes setup to collide two delayed, high-intensity laser pulses in a shared focus
Uses same optics to focus both pulses; one reflects back to collide with other
Imprints shadow in beam profile; signal photons scatter into this dark region
Models signal photon yields for different laser polarizations
Estimates 0.2 flipped photons per shot for optimized configuration

Measuring light-light scattering with high power lasers
This paper puts forward an experimental design to detect light-by-light scattering using two tightly focused, high-intensity laser beams. It employs a 'dark field' technique to measure the faint quantum vacuum response amidst the intense laser light. The authors model prospective signal photon counts for various laser polarizations.
