Figure 6. Lasing in muscle tissue with FITC conjugates.

Figure 6

a, Confocal fluorescence image of the muscle tissue stained with FITC-phalloidin. The muscle was arranged longitudinally. b, Spectrally integrated (530 nm – 545 nm) laser output as a function of pump energy density extracted from Fig. S10 . Solid line is the linear fit above the threshold, which is approximately 130 μJ/mm2. c, CCD images of lasing emission above the lasing threshold. All scale bars, 20 μm. Tissue thickness=30 μm. [FITC-phalloidin]=10 μM. Excitation wavelength=465 nm.
