Analysis of CW Oxygen-Iodine Laser Performance Using Similarity Criteria

Kinetics of oxygen species in an electrically driven singlet oxygen generator

“…The most active processes involving electrons and ions in the discharge zone that can contribute to the kinetics of these species are listed in Table 1 (processes [13][14][15][16][17][18]. For the typical electric discharge O 2 (a 1 ∆) generator conditions [30] .…”

“…There has been a long standing interest in the possibility of developing a discharge driven oxygen iodine laser (DOIL), where O 2 (a 1 ∆) is produced via electric discharge [7][8][9][10][11][12][13]. In the DOIL devices investigated todate [12], the low small-signal gain of the active medium has prevented the efficient extraction the energy stored in singlet oxygen O 2 (a 1 ∆) [17]. To increase the gain, the O 2 (a 1 ∆) concentration must be increased [8].…”

Features of power extraction in EOIL

“…where η extm =Y 0 -ΔY loss -Y d is the medium extraction efficiency 11 , ΔY loss =ΔY diss +ΔY relax is the sum of the yield of singlet oxygen loss due to the processes of iodine molecules dissociation ΔY diss and relaxation ΔY relax , Y d is the singlet oxygen yield at the output of the resonator.…”

“…7). This presents a real challenge for energy extraction from the EOIL active medium 10,11 . A number of papers [5][6][7][8] is devoted to the experimental study of cw EOIL energy performance.…”

“…A number of papers [5][6][7][8] is devoted to the experimental study of cw EOIL energy performance. Carroll and co-workers 6 obtained the record output power characteristics, but even they extracted only about 40 % of accessible energy 11 . In this paper, we apply a single-frequency two-level (SFTL) generation model including relaxation processes in an attempt to find the ways for increasing of the EOIL power performance.…”
