Preliminary investigation of applying nonlinear optical effects in conjunction with the optogalvanic effect to achieve laser controlled opening switch was proposed in the low cost grant. It should be mentioned at the onset that this work was limited by the budget and that its purpose was mainly to define the problems and establish feasibilities. A crucial step is a match of mutual virtual level. Within the budget limitation, a few important steps were made a Detailed study of the plasma processes taking a major role in the opto-galvanic effect such as Penning ionization and direct electron impact inoization and their relative importance b the use of dye lasers according to the Raman scheme c Penning ionization in HgNe and SrNe3 has been studied within the grant. A recent investigation the role of direct electron multistep ionization. The consequences are that although Penning ionization is an important process in the discharge it does not control it sustaining the discharge. In investigating the nonlinear effect little progress was made other than formalizing and defining the problems. Author
