Phenomenological model for mixed multiphoton absorption in bialkali photocathode and application to ultrafast pulse characterization

2019 · Applied Physics Letters

We propose a phenomenological model composed of concise formulas to describe mixed multiphoton absorption (MPA), revealing its quasi-exponent-function in relation to intensity, complicated spectral features, and polarization dependence, and then demonstrate it perfectly by experiments …
