In order to obtain super-resolved images, STED nanoscopy uses a laser tuned at the red tail of the emission spectrum of the fluorophore to deplete the excited state by stimulated emission. Since the stimulated emission cross section follows practically the same dependency with wavelength as the emission, this configuration involves very small cross sections and therefore high levels or irradiance. In a recent publication in Journal of Physics D, we show that STED nanoscopy is also feasible using wavelengths at the emission maximum, which reduces considerably the light dose required for super-resolution and extends considerably universe of fluorophores suitable for STED.
