Future work should investigate the presence of this observed motion in a point scanning-based PARS microscopy system using methods capable of detecting localized sample displacement with high sensitivity, such as phase-contrast OCT30 and laser Doppler vibrometry31, although it should be noted that ...
. Different numbers of radial intensity maxima confirm a strong mode group selectivity of mode-multiplexer and fiber.dWavelength-dependent attenuation measurements of the 23 km long 15-mode fiber. The fifth mode group has a higher attenuation, attributed to increased micro-bending sensitivity....
The cathode current (ic) is estimated based on the radiant sensitivity of the PMT (S) and the power of fluorescent emission incident on the PMT using ic = SηϕfσIVCf, where S = 50 mA W−1, η is the collection efficiency of the optics, ϕf = 0.93 is the...
