ABSTRACT
The performance of a 1-J XeCl excimer laser with a variable reflectivity mirror unstable resonator optical cavity is described. The output beam exhibits a flat profile in the near field and a far-field energy distribution with approximately 63% of the energy contained within an angle of 39 microrad (1/e(2) spot size).
ABSTRACT
The design and performance of various optical resonator cavities are described for a 1-J XeCl discharge laser with a 200-ns FWHM optical pulse. Advantages inherent in many cavity round trips for efficiently controlling linewidth, spatial coherence, and polarization are indicated.
ABSTRACT
The performance of an integrated master-oscillator-power-amplifier optical cavity to extract polarized, linenarrowed, tunable, and near-diffraction-limited radiation efficiently from a long-pulse wide-aperture electric discharge XeCl excimer laser is described. Pulse energies of 600 mJ with signal purity exceeding 95% have been achieved from a single laser.
ABSTRACT
The near- and far-field performance of three practical positive branch unstable resonator designs was compared for a commercial excimer laser operating on ArF and KrF. Atmospheric attenuation at 193 and 248 nm was measured.
ABSTRACT
Spectral purity of pulsed dye lasers is discussed with regard to signal, noise, and background radiation. Temporal and spatial measurements of these parameters are presented for an excimer-pumped dye laser.
ABSTRACT
Tunable, coherent vacuum-ultraviolet (VUV) radiation has been produced in the 1210-1290-A region by four-wave sum mixing in magnesium vapor. This important extension of the wavelength range of tunable radiation was achieved using KrF-laser-pumped uv dye lasers, whose sum frequency then directly overlapped the first odd-parity autoionizing state in magnesium. With powers of 10 kW in the fundamental dye-laser beams, a flux >/=10(8) photons per pulse was produced at Lyman-alpha, with higher intensities at the longer wavelengths.
