| Abstract: | We are reporting a theoretical prediction: The photoelectrons forming above-threshold-ionization (ATI) peaks emit both even and odd harmonics. These harmonics exhibit plateau and cut-off features similar to those odd-only harmonics observed in ATI experiments. |
| Keywords: | strong-field laser physics above-threshold inoization high harmonic generation evenodd harmonics nonperturbative quantum electrodynamics |
