Recent laser experiments on the Aurora KrF/ICF laser system

The Aurora KrF/ICF Laser Facility at Los Alamos is operational at the kilojoule-level for both laser and target experiments. We report on recent laser experiments on the system and resulting system improvements. 3 refs., 4 figs.

The Los Alamos bright sources: Review of the physics and the diagnostic technology

The investigation of many interesting physical phenomena in nature requires the generation of high-energy-density fields. To produce energy densities exceeding 10/sup 7/ J/cm/sup 3/ requires focusing a very powerful, very bright, short pulse laser. This talk will present a review of the physics that will be investigated with one such laser system, will describe the laser used, will describe the laser diagnostics, and will describe the physics diagnostics. The talk will emphasize the areas of re… more

Ultrahigh-brightness XeC1 laser system

A laser system that produces terawatt-level pulses of 308-nm light with near-diffraction-limited beam quality is under development. Pulses of 175-fs duration are generated at 616 nm in a synchronously-pumped mode-locked dye oscillator. These pulses are amplified in a three-stage dye amplifier longitudinally pumped by the frequency-doubled output of a regenerative Nd:YAG amplifier. Output of the dye amplifier is frequency-doubled in a BBO crystal and amplified in a chain of XeCl excimer stages. … more

Subpicosecond, high-brightness excimer laser systems

Subpicosecond, high-brightness excimer laser systems are being used to explore the interaction of intense coherent ultraviolet radiation with matter. Applications of current systems include generation of picosecond x-ray pulses, investigation of possible x-ray laser pumping schemes, studies of multiphoton phenomena in atomic species, and time-resolved photochemistry. These systems, based on the amplification of subpicosecond pulses in small aperture (/approximately/1 cm/sup 2/) XeCl or KrF ampl… more

Characterization of a high-intensity subpicosecond XeCl laser system

Recent advances in ultrafast lasers and large-aperture optical amplifiers have spurred the development of terawatt-class laser systems capable of delivering focal-spot intensities in excess of 10{sup 19} W/cm{sup 2}. At these extremely high intensities, the optical field strength is more than twenty times larger than the Bohr electric field, e/a{sub o}{sup 2}, permitting for the first time investigations of the optical properties of matter in a previously unexplored intensity regime. We describ… more

Recent advances in ultraviolet laser technology

The science and technology of violet and ultraviolet lasers has matured rapidly in the last five years. High average power lasers have been demonstrated and several commercial product lines are now available. Single pulse devices have successfully demonstrated large output energies in well controlled beams. In this presentation we will review some of the current laser development programs in progress at Los Alamos. We will describe research in both discharge pumped lasers and E-beam pumped lase… more

Acoustic gas analyzer. [To determine mole fraction of UF/sub 6/ in N/sub 2/]

A gas analyzer was developed to determine the mole fraction of UF/sub 6/ in N/sub 2/. It can be generally applied to any two component gas mixures, but it exhibits high resolution for gases with large differences in molecular weight. The theory of operation, design and performance of this analyzer for two component gas samples of UF/sub 6/ and N/sub 2/ is illustrated.

Fiber-optic coupled pressure transducer

A fiber-optic coupled pressure transducer was developed for measurement of pressure transients produced by fast electrical discharges in laser cavities. A detailed description of the design and performance will be given. Shock tube performance and measurements in direct electrical discharge regions will be presented.
