新しい 5592Å Xeイオンレーザー

抄録

New laser oscillation in ionized xenon at 5591±2Å has been obtained by the use of pulse excitation supplied by capacitive dis-charge at a low pressure (0.02_??_0.04 Torr). This oscillation is dominant in a rather longer current pulse duration, which seems to sug-gest the possibility of cw oscillation, whereas the seven already known XeIII and XeII laser lines (4954, 5008, 5159, 5260 or 5262, 5353, 5395 and 5971 Å) observed by the same appar-atus oscillate exclusively under the excitation of the shorter pulse and higher peak current. The new line was tentatively assigned to XeII 7 s'²D_3/2 -6 P'²D_3/2 transition, 5591.6Å. It is also shown that the output of pulsed ion laser is much influenced by not only the cur-rent density but the current pulse duration.
