Dependence of the PIV on the quarter-wave plate rotation angle φ at α = 45° and laser pulse energy of 0.68 mJ. The red line shows fitting the experimental data using Eq. (5) at n = 1.1 + i 1.59 and μ = 1.06. The blue and green lines show the helicity-sensitive and helicity-insensitive contributions, respectively, at U 1 = 3.15 mV and U 2 = 0.49 mV
