Nonlinear atomic tunnelling boosted by bright squeezed vacuum

The End of the “Brute Force” Era in Laser Physics For decades, the mantra of high-intensity laser physics has been simple: if you want a stronger reaction from an atom, you need a bigger laser. This “brute force” approach—ramping up classical intensity to trigger nonlinear processes like tunnelling ionization—has a ceiling. Eventually, you hit the … Read more
