Calibration of PTM resolution using reference standards. A,. MRS-4 reference standard (from top to bottom): schematic of sample, scanning electron microscopy (SEM), optical, and linear PT, respectively. Scale bar is 250 nm.B, PT imaging of a single 75-nm gold nanowire. C, Lateral and axial resolution of confocal PTM. Laser pump parameters: wavelength, 532 nm; energy fluence, 100 mJ/cm2; beam diameter, 250 nm. Panels A and C were adopted from Ref #14.
