So it is unwise to assume that a sine wave input to local-oscillator guarantees fewer harmonics at mixer output. The local oscillator port of a saturated-switch type mixer described above should be assumed non-linear. Driving a local-oscillator port with logic signals can be done, but not casually. A mixer local oscillator port often …

We report on an all-solid-state light source for nanosecond (ns) laser pulses, with broad tunability in the mid-infrared, spectral bandwidth close to the Fourier transform limit, and pulse energy in the mJ regime. To this end, we extend a tunable, continuous wave (cw) singly resonant optical parametric oscillator by an optical parametric pre-amplifier …

Early works indicated that the four-wave mixing (FWM) and self-phase modulation are important physical aspects for the spectral broadening [9], [10] in the fibers. Recent references have convinced that the FWM among multiple longitudinal modes results in the spectral broadening of fiber laser oscillator with FBGs [10] .

RECIPROCAL MIXING. Reciprocal mixing occurs when noise sidebands from the local oscillator (LO) signal in a superheterodyne receiver mix with a strong undesired signal that is close to the desired signal. Every oscillator signal produces noise, and that noise tends to amplitude modulate the oscillator's output signal.
