Experimental setup. The schematic diagram shows expansion of linearly polarized fiber laser light onto a spatial light modulator (SLM) using lenses F1 (f = 100 mm) and F2 (f = 200 mm). A second telescope (lenses F3 and F4, f = 500 mm) produces a plane conjugate to the surface of the SLM at the back aperture of the microscope objective (20x objective lens shown). CCD = charge coupled device, for recording images.
