In nonlinear microscopy, phase-only spatial light modulators (SLMs) allow
achieving simultaneous two-photon excitation and fluorescence emission from specific regionof-interests (ROIs). However, as iterative Fourier transform algorithms (IFTAs) can only
approximate the illumination of selected ROIs, both image formation and/or signal acquisition
can be largely affected by the spatial irregularities of the illumination patterns and the speckle
noise. To overcome these limitations, we propose an alternative complex illumination method
(CIM) able to generate simultaneous excitation of large-area ROIs with full control over the
amplitude and phase of light and reduced speckle. As a proof-of-concept we experimentally
demonstrate single-photon and second harmonic generation (SHG) with structured
illumination over large-area ROIs. [-]
