Lamb Shift Studies of Cl16+l 17+ beam from the Brookhaven National Laboratory double MP Tandem accelerator facility that had been partially promoted into the excited 2s.. metastable state of the one electron ion (Cl 16+). The 2s. —2p., Lamb Shift transition in this ion was driven by the E-field from a powerful CO. laser. The

Resonance Ionization Spectroscopy: Counting Noble Gas Atomsy selective and has one-atom sensitivity. Prior to the development of RIS for sensitive analytical purposes, similar laser ionization schemes were proposed for the separation of isotopes. Two-step selective photoionization of Rb atoms was reported by AMBARTSUMYAN, KALININ, and LETOKHOV in 19

Linewidth Characteristics of (GaA1)As Semiconductor Diode Lasersorted here is a study of the power and temperature dependence of the fundamental linewidth of continuously operating (GaAl)As single mode diode lasers. The linewidths were observed to decrease linearly with reciprocal output power with a slope significantly greater than the calculated Schawlow-Towne

High Sensitivity Spectroscopy with Tunable Diode Lasers — Detection of O2 Quadrupole Transitions andtions of TDLs utilise only the tunability and high resolution of these devices, and few experiments have employed the ability of the TDL to detect very small absorption coefficients. We have developed a laser absorption spectrometer (LAS) which can detect absorption coefficients as small as 10. to l

Stark Modulation Spectroscopy in the Visible Regionn microwave spectroscopy and recently in infrared spectroscopy. By means of the Stark modulation technique very high sensitivities can be achieved and, at the same time, important clues for the assignment of absorption lines are obtainable. Although the potential usefulness of this technique using a
