Second harmonic hectometric radio emission at Jupiter

Radio Emission from Jupiter

Three reviews of radio emission from Jupiter have appeared recently (1, 2, 3) and at least one more is currently in press. The present review primarily covers work since 1961. It would be not too strong to suggest that explanations of Jupiter's emission now are in the second generation, with most observational phenomena fairly well established. The salient observed features are not widely known...

Explanation of dominant oblique radio emission at Jupiter and comparison to the terrestrial case

The Io-Jupiter S-bursts are series of quasi-periodic impulsive decameter radio emissions from the magnetic flux tube connecting Jupiter to its closest galilean satellite Io. This paper discusses the possibility, suggested by previous works by Hess et al, that the S-bursts are triggered by upgoing electrons accelerated (downward) by trapped Alfvén waves, that have mirrored above the Jupiter iono...

Second-Harmonic Emission from Quantum Cascade Lasers

The mid-infrared spectral region can be covered by quantum cascade (QC) semiconductor lasers, where the emission wavelength is tailored by bandstructure engineering. For a detailed review on QC lasers see Ref. [1]. Their emission energy is well below the band gaps of the hosting material system. Typical GaAs QC lasers operate in the mid-infrared regime with corresponding energies of ~100 meV, w...

Enhanced Čerenkov second-harmonic emission in nonlinear photonic structures.

We study experimentally and theoretically the Čerenkov-type second-harmonic generation in a one-dimensional nonlinear photonic crystal. We demonstrate that the power of emitted second-harmonic can be enhanced 270 times by varying the angle of incidence of the fundamental beam such that the reciprocal lattice vector of the crystal can be used to compensate for the phase mismatch in the transvers...
