For the creation OPD is proposed to use powerful pulse - periodic (P-P) laser radiation with duration of pulses ~ 100 - 150 ns and high pulse repetition frequency ~ 50 - 100 kHz. OPD is formed with the help of matrix of reflectors (MR). This is allowed: several times to increase the effectiveness of laser emission use for purposes of LJE creation, to avoid strong impact loads on the apparatus, to exclude the thermal action of laser plasma on the reflector, to decrease the laser emission screening by plasma, to remove the problem of the resonance oscillations appearance into the object moved with the help of laser. In our article the estimations of possible LJE thrust levels under the conditions of the proposed mechanism of reactive motion are given. Also, the new approaches to the creation of the high power high repetition rate laser systems for the “Impulsar” program are examined.展开更多

These works are the prolongation and development of Tesla studies in the beginning of XX century. In particular, not so long ago highly effective energy transfer between two resonant circuits, connected by very thin wire (100 mkm) with more than kilometer length had been demonstrated. In these experiments Tesla type transformers with the output voltage about several ten kilovolts and output power up to 10 kW were used [1]. An effective replacement of wire by laser-plasma channel in that configuration of experiment would be the obvious improvement of demonstrated technology.展开更多
