First demonstrated over fifty years ago, carbon monoxide (CO) and carbon dioxide (CO2) lasers are similar technologies that took two different paths of development. CO2 lasers are deployed extensively in a wide range of industrial applications, and t

Laser Micromachining is well established in industry. Depending on the application lasers with pulse length from μseconds to femtoseconds and wavelengths from 1064nm and its harmonics up to 5μm or 10.6μm are used. Ultrafast laser machining using p

The external electric field switching technique is applied to the autoionizing Rydberg states of xenon which produces highly stable long-lived ZEKE states. The experiment illustrates that the enhancement process occurs via an externally induced l-loc

The pulsed field ionization zero-kinetic-energy (PFI-ZEKE) spectra of o-, m- and p-xylene have been recorded and analyzed. These clearly demonstrate neighboring methyl groups to be interacting and ...

A new electric field switching technique is demonstrated which converts Rydberg states into highly stable long-lived ZEKE states (high- l ) as low as n=45. The stability of these states is further improved by adding a subsequent pulse rotated by π/2

The present letter outlines a proposal in the form of a practical method to externally induce the stability of high-n Rydberg states otherwise subject to intramolecular decay or autoionization. The method employs the fast switching of a DC electric f

Zero-kinetic energy states are highly stabilized Rydberg states that reside below each ionic eigenstate of a molecular system. The high resolution detection of these states constitutes a high resolution spectroscopy for molecular ions. Zero-kinetic e
