dual-color STED nanoscopy (Fig. 1) and molecular diffu-sion quantiﬁcation down to ~20 nm in (living) cells. The presented dual-channel STED microscope utilizes a single ﬁber laser providing a 20-MHz train of 775 nm wavelength pulses of 1.2-ns duration. This compact laser source en-ables STED on ﬂuorophores emitting in the orange to red range.

Following conventional wisdom, the resolution of light microscopy is limited by diffraction to about half the wavelength of light, which is why conventional light microscopes fail to distinguish object details that are closer together than ~200 nanometers.

STED nanoscopy is based on the reversible inhibition of ﬂuorescence emis-sion of a marker by stimulated emission. The stimulated emission is induced by the STED light at a wavelength that is typically at the red edge of the emission spectrum.

Digitally enhanced STED nanoscopy can achieve a spatial resolution of ~λ/8 at a depletion power of 1.4 mW. Depletion power at this order of magnitude is 10 times lower than that in traditional STED imaging, and it will substantially reduce the damage to biological samples and the bleaching of fluorophores.

Our results provide the ﬁrst practical evidence that far-ﬁeld optical nanoscopy of highly dynamic samples is possible. 2.
