Ultrafast laser-induced electron emission from multiphoton to optical tunneling
Based on a time-dependent quantum model, a relation between the onset of the optical tunneling regime and the metal work function is determined. In the multiphoton regime, the number of photons required for absorption is reduced from n=3 (at pulse length τ>20 fs) to n=2 (at τ<8 fs) due to the...
