When a plane finite‐amplitude wave of frequency f 1 interacts with a plane small‐signal wave of higher frequency f 2, side‐bands at frequencies f 2±nf 1 are produced while the amplitude of the f 2 signal is reduced. Two models have been used to predict the spectrum. The first is ...

Control over the intensity, shape, direction and phase of coherent light is essential in numerous fields, from gravitational wave astronomy, quantum metrology and ultrafast sciences to semiconductor fabrication. Modern photonics, however, can involve parameter regimes where the wavelength or high optical ...
Modulation of the propagation of short wind waves by the dominant long wind wave components is investigated in a laboratory experiment. The theoretical predictions are confirmed by the observed three dimensional frequency-wavenumber spectra of short waves. 关键词: gravity waves ocean waves oceanographic ...
The second current (I2), is a bit stream with pulse lengths smaller than the thermal time constant of the laser. I1 affects the temperature in the active zone of the laser whereas I2 is too short to significantly affect it. The wavelenth, lambda, along the emission axis is temperature ...
The hydrodynamic modulation of short surface waves by swell is measured with stereophotography and a laser-slope sensor. The results are consistent with the relaxation model introduced by Keller and Wright (1975). A comparison with the modulation transfe
A lightwave modulated by V-band millimeter waves was obtained from a 5-GHz electric signal. The spectrum linewidths of the generated 60-GHz millimeter wave was smaller than 300 Hz. By using mode-coupling equations, the spectra of the output lightwave were theoretically calculated. It was shown...
