摘要

Microwave discharge of a Cl_(2)/He mixture as a simple, clean and efficient Cl atom generator was used for an all gas-phase iodine laser study. Sufficient NCl(a~(1)(DELTA)) was produced through the reaction of HN_(3) + 2Cl -> NCl(a~(1)(DELTA)) + HCl + N_(2). The energy transfer reaction of I(~(2)P_(3 2)) + NCl(a~(1)(DELTA)) -> I(~(2)P_(1 2)) + NCl(X~(3)(SIGMA)) was observed. A population inversion was observed directly by using a 1315 nm tunable diode laser by scanning the entire line shape of the (3,4) hyperfine transition of iodine, and a small signal gain of 5 X 10~(-5) cm~(-1) was obtained.
