Inducing photosynthesis with laser light is feasible as long as the light's wavelength is appropriate. Research indicates that various light sources, including lasers, can effectively facilitate photosynthesis. Notably, ultrafast lasers have been utilized in advanced studies to investigate electron transfer reactions during the process. A significant technique developed by Fleming's research group, known as two-dimensional electronic spectroscopy, allows scientists to track light-induced excitation energy flow through molecular complexes with femtosecond precision. This method employs multiple laser beams to sequentially flash samples, enabling detailed observation of how excitation energy is transferred between molecules, thereby altering their light absorption and emission properties.
