Dissociation of molecular iodine in RF discharge for oxygen-iodine lasers

Heterogeneous losses of externally generated I atoms for OIL

“…Jirasek et al 9 used 40 MHz discharge with coaxial electrodes using I 2 as a precursor in Ar carrier gas. Core electrode was made from tungsten whereas exterior one was made from aluminum.…”

“…Electric-discharge [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] and chemical [18][19][20] generators have been proposed as a source of iodine atoms for the use in OIL. Dissociation of iodine-containing molecules in electric-discharge plasmas had been proved to be useful for external production of iodine atoms.…”

“…Schmiedberger et al 8 and Jirasek et al 9,10 studied generation of atomic iodine by dissociation of CF 3 I, CH 3 I or I 2 in a RF discharge. They found that dissociation efficiency was better with I 2 as a precursor in Ar carrier gas.…”

Influence of molecular oxygen on iodine atoms production in an RF discharge

“…Argon (Ar) proved to be the best carrier gas for the dissociation of iodine precursors, because in mixtures with Ar the highest dissociation efficiency was obtained [9,10]. However, discharge stability becomes a problem, with an increase of a precursor partial pressure.…”
