Notes:
We have designed a multipulse laser system to measure nanosecond time scale, plasma-density gradients by moiré deflectometry. The complete system consists of four, transverse-excited, atmospheric pressure (TEA) N2 laser oscillators and two low-pressure N2 laser amplifiers; two oscillator pulses are injected into a single amplifier. The amplified pulses are less than 1 ns in duration, with a variable, interpulse time of 4–10 ns. As described here, two TEA oscillators and a single amplifier were used to image air-density gradients in an expanding, air-shock wave produced by a spark discharge. © 1996 American Institute of Physics.
