Over 1-mJ Intense Ultrashort Optical-Vortex Pulse Generation with Programmable Topological-Charge Control by Chirped-Pulse Amplification

摘要

We demonstrated the generation of over 1-mJ intense optical-vortex pulses of which topological charges were programmable controlled by computer-generated holograms. The pulse duration was characterized to be 27 fs by two-dimensional spectral shearing interferometry.
