Depolarizing Collisions in Nonlinear Electrodynamics by Igor V. Yevseyev, Valery M. Yermachenko, Vitaly V. Samartsev


By Igor V. Yevseyev, Valery M. Yermachenko, Vitaly V. Samartsev

During this publication, the authors derive the speculation of elastic depolarizing collisions and describe their significance in a few nonlinear electromagnetic phenomena in gaseous media. The formation of photon echo and an outline of its a variety of forms in gaseous media are then provided. The authors convey that the features of the corresponding signs count basically on elastic depolarizing collisions. in addition they reflect on some great benefits of a brand new form of photon echo spectroscopy: polarization photon echo-spectroscopy. A high-level, really expert remedy, Depolarizing Collisions in Nonlinear Electrodynamics will attract researchers and complex graduates in nonlinear optics and quantum electronics.

05 and, therefore, is not shown in Fig. 4. 23) For |t| <<1 and |t| >>1 this is true for all values of S. Also, in the region where |S| > 3 the functions F(S, t)(κ) are weakly dependent on parameter t. The behavior of the functions ReF(S, t)(0), ReF(S, t)(1) and ReF(S, t)(2) differs drastically for small values of S and for values of t on the order of unity. From Fig. 3 it follows that at t=1 the function ReF(S, t)(0) tends to zero as S→0, while ReF(S, t)(1) and ReF(S, t)(2) tend to values on the order of unity.

For this reason the fractional difference in the functions, say, (F(S, t)(1)– F(S, t)(2))/F(S, t)(1), is proportional to t/S2 in this range of values of the parameters. 5. Parameter S took on the values 0, ±1, ±2,… , ±10. Within the accuracy of calculations (≈20%) these functions coincide and are weakly dependent on parameter t. 42). To establish the dependence of the F(S, t)(κ) on the index κ the differences Re(F(S, t)(3)– F(S, t)(0)) and Im(F(S, t)(3) –F(S, t)(1)) were calculated with enhanced accuracy.
