Numerical study demonstrates that optimized laser diodes enhance high-resolution biomedical imaging with reduced excitation confinement.

To investigate a novel phase-shifted excitation strategy for photoacoustic microscopy enhancing resolution.
Conducted numerical simulations for Gaussian and donut beam excitation.
Analyzed the effects of the optical power ratio between beams on resolution.
Evaluated full width at half maximum for different beam configurations.
Achieved a ~1.42-fold enhancement in lateral resolution.
Reduced full width at half maximum from 1.177 to 0.828 units.
Identified an optimal optical power ratio of 1.16 for excitation efficiency.

George J. Tserevelakis (2026) studied this question.
