A continuously pumped Nd:YLF regenerative amplifier has been developed that can amplify 40-psec pulses at a repetition rate of greater than 10 kHz, with an average power in excess of 5 W. Pulse energies are as high as 2.0 mJ at 3 kHz and 640 microJ at 10.5 kHz. The limitation on the amplifier repetition rate that is associated with piezoelectric ringing in(More)
The objective of this study was to develop a chronic bioassay technique to rapidly screen chemicals for potential toxic effects. The phototactic behavior of Daphnia magna was used for that purpose. Negative phototaxis was elicited by switching the direction of light imposed on a population of 20 adult Daphnia. The percent population that responded by(More)

A stable, closely-controlled, high-intensity, single-bunch beam will be required for the SLAC Linear Collider. The characteristics of short-pulse, low-intensity beams in the SLAC linac have been studied. A new, high-intensity thermionic gun, subharmonic buncher and S-band buncherl accelerator section were installed recently at SLAC. With these components,(More)
Above-band-gap picosecond pulses are used to generate holographically high-frequency, coherent, surface acoustic modes on semiconductor surfaces. Optical diffraction from the surface acoustics is in superposition to a free-carrier phase grating that acts as an amplifying cross term in the diffraction process. The detection limits are of the order of 10(-4)(More)
Pairs of orangespotted sunfish were exposed to oil refinery wastewaters in acute, non-lethal toxicity tests. Frequencies of agonistic behaviors (approaches, fin erections, tail beats, operculum spreads, chases, bites and avoidances) were determined initially after a 10-d exposure to control water and then again after a 10-d exposure to the wastewaters.(More)
We demonstrate reliable operation of a stable synchronously pumped dye amplifier for femtosecond pulses from a passively mode-locked dye laser. Conversion efficiencies of 8% are obtained with output powers of 40 mW and 50-fs pulse widths at repetition rates of up to 10 kHz with pulse energy stability of 3% rms. Synchronization is achieved by driving the(More)
