An approach to rapid soil testing which involved the use of simple solvent extraction methods was developed. The analytes of interest were priority pollutants of low water solubility which could not be readily removed from the soil using water. Direct toxicity testing of the soil samples by Microtox showed a high background toxicity which prevented(More)
Solid state regenerative amplifiers have proved to be a reliable source for producing stable millijoule pulses as short as a few picoseconds at repetition rates ranging from a few hertz to several kilohertz. Here we report on the operation of a cw pumped Nd:YLF regenerative amplifier that uses a convex-concave design to optimize output energy and stability(More)
