BRIEF COMMUNICATIONS: Observation of saturated absorption resonances in a molecular I2 beam subjected to separated fields
The Doppler broadening of the absorption lines of the I2 molecules was suppressed by a combination of the saturated absorption and molecular beam methods. Saturated absorption resonances were observed at the components of the hyperfine structure of the P(13) and R(15) branches of the lΣ+g(X)→3ΠOU+(B) electronic transition in the I2 molecules subjected to 514.5 nm radiation from an argon laser. The optical fields were separated spatially by 3.5 cm along the molecular beam. The advantages of this method of inducing narrow resonances were considered from the point of view of their reproducibility.
