Advanced Applications
... The second beam, the probe beam, will go through the gas cell and be detected by one port of a balanced detector. The frequency of this beam is identical to that of the pump beam but propagates in the opposite direction; thus the Doppler shift observed from this beam is of opposite sign. Hence, only ...

Time-resolved detection of propagating Lamb waves in thin
... In the spectra with the spatially separated pump and probe, the 58.4 GHz mode has the largest amplitude. It corresponds to a Lamb wave of 100 nm wavelength with a phase velocity of about 5840 m/s, which is close to the transversal speed of sound in bulk Si. We attribute the large amplitude to the fa ...

Electromagnetic Radiation (EMR) and Remote Sensing
... Every natural and artificial object reflects and emits EMR over a range of wavelengths in its own chemical composition and physical state. The distinctive reflectance and emission properties of objects are called spectral signature. Within some limited wavelength region, a particular object will usu ...

Enhanced visualization of choroidal vessels using ultrahigh
... As demonstrated in Fig. 1, ophthalmic ultrahigh resolution OCT operating in the ~800 nm wavelength range does not provide sufficient access to the choroid when the RPE layer is intact. Considering that absorption of light from melanin, the major chromophore in the RPE, decreases monotonically with i ...
