Powder method of measuring the noncritical phase-matching frequency

Nonlinear optical properties of new molecular crystals

“…90°-phase matching frequency determination by powder method (Ref. 5) shows that this transformation regime takes place at wavelength close to 1.06 1um. It seems to us that semicarbazone of 5-nitrofurfural crystals may appear to be sufficiently effective for the nonlinear frequency transformations.…”

“…(5) If the interference quality is satisfactory (a> 0.3), the calculations of nonlinear susceptibility values according to (4) and (5) give less than 10% difference. The difference of the correcting factors is maximal when the interference pattern is not observed (a = 0), but in this case it is easy to determine the reason of FIB absence, e.g.…”

Instability of quark matter core in a compact newborn neutron star with moderately strong magnetic field

“…The studies on the effect of strong magnetic field on various physical processes, relevant for these exotic objects have been reported during the past few years. These studies are mainly related to the equation of states of dense matter [7][8][9], elementary processesspecially weak and electromagnetic decays and reactions [10], quark-hadron phase transition [11][12][13], and transport coefficients of dense matter [14]. A few years ago we have shown explicitly that a first order quark-hadron phase transition is absolutely forbidden in presence of strong magnetic field (≥ a few times 10 15 Gauss [11,12]).…”
