Phase-of-the-phase spectroscopy as a tool to calibrate a laser — •Felix Trepkau, Vasily Tulsky, and Dieter Bauer — University of Rostock, 18051 Rostock, Germany

We present a way to accurately calibrate a two-color bi-circular laser field. Such laser configurations have recently attracted special attention due to well-defined angular properties of photoelectrons that they create while interacting with matter. The calibration technique we propose is based on the phase-of-the-phase spectroscopy and relies on sharp intensity-sensitive features in the photoelectron signal [1-2].
