Experimental setup. Laser – Verdi V10 (Coherent, vacuum wavelength 532 nm), AOD – acousto-optical deflector R35085-3 (Gooch&Housego), lens L1 – AC254-050-A (f1 = 50 mm, Thorlabs), spatial filter SF1 – high-power precision pinhole P25C (ϕ25 μm, Thorlabs), lens L2 – AC254-300-A (f2 = 300 mm, Thorlabs), SLM – spatial light modulator HSP512-532-PCIe (Meadowlark Optics), lens L3 – AC508-500-A (f3 = 500 mm, Thorlabs), M1, M2 – broadband dielectric mirrors BB1-E02 (Thorlabs), spatial filter SF2 – iris aperture SM1D12D (Thorlabs), lens L4 – AC254-150-A (Thorlabs), DM - dichroic mirror (made in-house), objective – PlanC N 40x/0.65 (Olympus), combined motorized microstage and piezo-driven nanostage – NanoView (MadCityLabs), GM – protected gold mirror PF10-03-M01 (Thorlabs), tube lens TL – AC254-200-A (Thorlabs) and camera acA640-750-um (Basler). The Köhler illumination is built with IR filter to prevent sample heating.
