A prepulse-sustainer discharge circuit for excitation of a xenon chloride laser is described. A single thyratron switch is used to initiate an electrical sequence which preionizes, prepulses and sustains the electric discharge in the laser. Important

This study was performed to demonstrate selective uptake of hematoporphyrin derivative (HPD) within actively developing atheroma, to localize the site of uptake of HPD within the atheroma, and to determine the potential for photodynamic therapy (PDT)

Seventy samples of human cadaver atherosclerotic aorta were irradiated in vitro using a 308 nm xenon chloride excimer laser. Energy per pulse, pulse duration and frequency were varied. For comparison, 60 segments were also irradiated with an argon io

Injection locking is investigated as a means for control of optical pulse duration and polarization in a XeF laser. Intense short‐pulse generation in the ultraviolet is achieved by injection of a low‐level 1‐ns optical pulse into a XeF oscillat

Pulse slicing and two-pass amplification are investigated as a means of producing high-energy subnanosecond pulses in the near ultraviolet. A simple laboratory-scale XeCl oscillator-Pockels cell pulse slicer-amplifier system is used to produce 50-mJ

A preionized transverse electric‐discharge‐pumped N+2 charge‐transfer laser oscillating on the (B2Σ+u−X2Σ+g) transition of N+2 is reported. Peak power of 180 kW in a 8‐nsec FWHM laser pulse has been obtained with a 0.1% mixture of N2 in h

A holographic grating at grazing angle of incidence was used to achieve tunable, narrow bandwidth (0.005 nm) operation of a XeCl oscillator for injection locking of a ring amplifier. The amplifier’s narrow bandwidth output energy was constant and e

A spectral linewidth of less than 70 fm and diffraction-limited beam divergence have been obtained from a long-pulse, electric-discharge xenon chloride laser with intracavity Fabry-Perot etalons. A gain duration of 100 ns provided for multipass opera

Single longitudinal mode output from a directly tuned, long pulse, magnetically switched XeCl laser is reported for the first time. Mode control was achieved using spatial aperatures and intracavity etalons. The narrow bandwidth laser output was diff
