Cascaded multi-harmonic generation in a \b{eta}-BBO crystal reaching 133 nm from a single 800 nm pump beam
J. Seres, E. Seres, T. Schumm
Nonlinear crystals are widely used to efficiently generate second or third harmonics, and also for frequency mixing. Generation of multiple cascaded harmonics simultaneously, howev…
