Research reveals incoherent radiation generates high harmonics, suggesting new insights into optical coherence properties.
Key Points
High harmonics can be generated using incoherent radiation, which contradicts traditional assumptions about electric fields.
The generated harmonics have zero electric field amplitudes, emphasizing their incoherent nature contrary to prior expectations.
Analysis of quantum states shows they follow photon number statistics but differ in coherence from coherent harmonics used before this work on high harmonic generation dynamics. The findings imply significant changes for conducting attosecond experiments, likely altering interpretations of harmonic radiation properties.
