For in-line generation of circularly polarized high harmonics
Following several queries, we decided to share supplemental technical information regarding the construction of MAZEL-TOV (MAch-ZEhnder-Less for Threefold Optical Virgina spiderwort) apparatus – our simple and robust device for in-line generation of circularly polarized high harmonics (see Kfir et al, Appl. Phys. Lett. 108 211106 (2016) and the demonstrative movie clip within it). When inserting a MAZEL-TOV device in the laser beam path of a standard system for HHG, the harmonic spectrum immediately changes from odd-harmonics with linear polarization to a typical spectrum of circularly polarized harmonics. The device can control the polarization of the generated high harmonics by rotation of a single quarter-waveplate.
