Infrared lasersThree investigations of difference frequency generation (DFG) of far-infrared radiation by optical mixing are described, i.e., a theory of DFG by monochromatic, focused Gaussian pump laser beams, a theory of DFG by a picosecond pump laser pulse, and an experiment using ruby-...

Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz). With the use of antennas and transmitters, an RF field can be used for...
A tunable color center laser has been used as the infrared radiation source for infrared-radio-frequency double resonance spectroscopy. The A 1– A 2 splitting ( J, K = 1, = 1 and J, K = 2, = 1) in the ν 4 vibrational state of CH 3F has been studied. This technique has also...

The target device achieves an ultrafast response of 19.7/18.3 ns in the frequency-selective photoresponse range 0.8–9.7 MHz. This anti-interference photodetector can accurately transmit character and video data under strong light interference with a source intensity of up to 454 mW cm...

The vibrational frequency is considered to be equal to the frequency of absorbed radiation (or frequency difference in the case of Raman) and is proportional to the energy difference, but it is customary to define its value not in hertz but in a frequency-dependent unit, the wavenumber, cm...

Simultaneously, cooling the external degrees of freedom restricts the distribution of velocities in the sample, resulting in narrower line-shapes, and raising the matter-radiation interaction time. Moreover, when using specimens in form of beams, spectra are also freed from collisional broadening ...
