Precision Measurement of the Ground State Lamb Shift in Hydrogen and Deuteriumperiment by W. E. LAMB and R. C. RETHERFORD the Lamb shift has been measured for a great many hydrogenic states, and such measurements are among the most precise tests of QED . One measurement which was conspicuously missing from this list, however, was the Lamb shift of the hydrogen ground s

Laser Frequency Measurements: A Review, Limitations, Extension to 197 THz (1.5μm) is due to their excellent frequency stability and accuracy, and the direct measurement of their frequencies. The measurement of both the frequency and wavelength of the CH. device yielded a hundred fold increase in the accuracy of the speed of light. This paper reports the extension of direct frequ

Selective Dissociation of Polyatomic Molecules by Two Infrared Pulsesing problems in laser physics and laser chemistry. The possibility that an isolated molecule, placed in the intense infrared field of a laser, can absorb many photons (enough to dissociate as a result of absorption) in a very short time span, was first suggested in 1971 by Isenor and Richardson

Laser Diode Spectra of Spherical-Top Moleculesr about 2 × 10. cm. . The potential usefulness of such a device for high-resolution absorption spectroscopy was immediately recognized , but progress remained slow because of the limited tuning ranges of the early diodes, and because many spectra recorded at this resolution reveal an almost em
