Just a couple of papers below that might be of interest to some Vorts…
Why couldn’t SPUC/SPDC be the mechanism channeling the excess energy into lower forms of energy (i.e, heat, phonons, lattice vibrations) in LENR? Instead of producing a few highly energetic particles, the energy is spread out amongst a larger population of lower forms of energy… -mark -------------------------------- Nonlocality - The party may be over! Trevor W. Marshall Dept. of Mathematics, University of Manchester, Manchester M13 9PL, U. K. Abstract We demonstrate that the phenomenon known as Spontaneous Parametric Down Conversion is really an amplification, in a nonlinear crystal pumped by a laser, of certain pairs of modes of the electromagnetic zero-point field. The demonstration is achieved by showing the existence of a related phenomenon, Spontaneous Parametric Up Conversion. This phenomenon, once observed, will cast doubt on the quantum-optical theory, which treats photons as the elementary objects of the light field. It will also lend greater credibility to the zero-point field description of optical entanglement phenomena. That description is based on the unquantized light field and is consistently local, in contrast with the nonlocal description of Quantum Optics. -------------------------------- Femtosecond spontaneous parametric upconversion and downconversion in a quadratic nonlinear medium Jinyu Sun, Shian Zhang, Tianqing Jia, Zugeng Wang, and Zhenrong Sun JOSA B, Vol. 26, Issue 3, pp. 549-553 (2009) http://dx.doi.org/10.1364/JOSAB.26.000549 Abstract Spontaneous parametric up-conversion (SPUC) and spontaneous parametric down-conversion (SPDC) have been observed in the β-barium borate (BBO) crystal, and their mechanisms are experimentally and theoretically investigated. SPUC, tuned from 530 to 600 nm with a FWHM of about 25 nm, can be attributed to the sum frequency between the quantum noise and the fundamental laser pulse in the type II phase matching condition (e+o→e). SPDC, tuned from 480 to 520 nm with a FWHM of about 15 nm, can be attributed to the difference frequency between the quantum noise and the fundamental laser pulse in the type I phase matching condition (e→o+o).
