Photoelectron emission from the valence band of a metal surface by ultra-short laser pulses is studied within the Band-Structure-Based - Volkov (BSB-V) approximation, which takes into account the contribution of the band structure of the solid. The BSB-V approach is applied to calculate differential electron emission probabilities for aluminum and beryllium surfaces. We found that band structure effects are extremely important for Be(0001), for which signatures of partially occupied surface states can be observed in the electron emission spectra.
