Ultraminiature high-power gas discharge lasers excited through high dielectric constant ceramic materials.

The authors show that millimeter-size high-pressure UV nitrogen lasers can be excited through high dielectric constant materials and provide peak beam powers of 10(4)-10(5) W.

Simple and compact photopreionization-stabilized excimer lasers.

A novel photopreionization-stabilized discharge scheme was developed to excite rare gas halogen excimer lasers with beam energies of 100-250 mJ. The scheme requires no auxiliary timing or switching circuits and provides for the construction of compact and reliable devices.

Ultraminiature high-power gas discharge lasers.

The authors describe the development of millimeter-size photopreionization stabilized atmospheric pressure uv nitrogen lasers. Sealed-off versions of these lasers can provide peak powers of 30-150 kW and average power of 1-5 mW. The discharge and pulsing concepts are very general and are being adapted to a variety of other high-pressure TE-type laser systems.
