Effects of intermodulation distortion on the performance of a hybrid radio/fiber system employing a self-pulsating laser diode transmitter [PDF]
, 2003 A self-pulsating laser is used to generate a multicarrier (five radio frequency (RF) channels) microwave optical signal for use in a hybrid radio/fiber system. The self-pulsation is achieved by external light injection into the laser diode.

Photonic RF Down-Converter Based on Optomechanical Oscillation [PDF]
, 2008 We demonstrate all-optical radio-frequency (RF) down-conversion in a silica microtoroid optomechanical (OM) oscillator. Preliminary results show that the OM oscillator can simultaneously serve as mixer and local oscillator in a photonic homodyne RF ...

Radio frequency (RF) heated supersonic flow laboratory [PDF]
26th Joint Propulsion Conference, 1990 A unique supersonic flow apparatus which employs an inductively-coupled, radio frequency (RF) torch to supply high enthalpy source gas to the nozzle inlet is described. The main features of this system are the plasma tube, a cooled nozzle assembly, and a combustion/expansion chamber with a heat exchanger.

Improving temporal resolution of ultrafast electron diffraction by eliminating arrival time jitter induced by radiofrequency bunch compression cavities [PDF]
, 2017 The temporal resolution of sub-relativistic ultrafast electron diffraction (UED) is generally limited by radio frequency (RF) phase and amplitude jitter of the RF lenses that are used to compress the electron pulses.
