Jj. Rocca et al., DISCHARGE-DRIVEN 46.9-NM AMPLIFIER WITH GAIN-LENGTH APPROACHING SATURATION, IEEE journal of selected topics in quantum electronics, 1(3), 1995, pp. 945-948
Gain length products up to gl approximate to 14 for the J = 0-1 line o
f Ne-like Ar at 46.9 nm have been achieved in 15-cm-long plasma column
s generated by a fast capillary discharge. Amplification in plasma col
umns up to 20 cm in length was investigated. The laser line intensity
is observed to increase exponentially for plasma lengths of up to 15 c
m, above which it is observed to saturate. The saturation behavior is
discussed.
