External-cavity frequency-stabilization of visible and infrared semiconductor lasers for high resolution spectroscopy
, Optics Communications, Vol: 85, Pages: 355-359, ISSN: 0030-4018We have shown that the external cavity stabilization can be a straightforward and powerful technique for converting diode lasers of poor spectral quality into useful tools for high precision laser spectroscopy. The method requires an anti-reflection coating on one facet of the diode laser but, contrary to popular belief, this is not difficult and does not require any specialized equipment. We describe a coating procedure which can be used with standard commercial diode lasers. We have demonstrated the external cavity method using diodes at a variety of visible and infrared wavelengths. Details are given for a visible laser centered at 670 nm. © 1991.

Search for time-reversal-symmetry violation in thallium fluoride using a jet source
, Physical Review A, Vol: 44, Pages: 2783-2799, ISSN: 1050-2947We have looked for a violation of time-reversal symmetry (T) in the molecule thallium fluoride using a rotationally cold beam from a jet source. Our method was to search for a frequency shift of the thallium nuclear magnetic resonance when an external electric field of 29.5 kV/cm was reversed with respect to a magnetic quantization axis. The measured shift, (1.42.4)×10-4 Hz, was interpreted as a null result and constitutes a tenfold improvement in sensitivity over the previous measurement. Accordingly, our measurement has reduced the upper limits on the proton and electron electric dipole moments and on other T-violating weak couplings that can be deduced from the frequency shift. © 1991 The American Physical Society.

RESONANT EXCITATION AND STABILIZATION OF RYDBERG ATOMIC LEVELS IN MULTIPHOTON IONIZATION IN A STRONG LASER FIELD
, ZHURNAL EKSPERIMENTALNOI I TEORETICHESKOI FIZIKI, Vol: 99, Pages: 411-428, ISSN: 0044-4510Resonant ionization of atoms in two fields - exciting (weak) and ionizing (strong), is considered under resonant conditions in the region of the Rydberg levels whose spectrum is restructured under the action of a strong ionizing field. The photoelectron energy spectrum and dispersion dependence of the ionization rate on the frequency of the exciting field are found. It is shown that under certain conditions the functions may have narrow minima in the vicinity of the electron energy and energy and exciting field frequency corresponding to the resonances on the quasi-energy atomic levels. The nature of the effect is elucidated and it is shown that it is due to interference between the direct resonant and cascade ionization processes. On this basis a physical interpretation of the stabilization of multiphoton ionization of atoms in the ground state located in a very strong laser field is presented. The case of short laser pulses with a smooth envelope and the specific features of the excitation and interference stabilization of the Rydberg levels which thus arise are considered.
