Description
A new technique is reported for in-situ, nonintrusive, and sensitive measurement of plasma electric fields with high spatial resolution (< or approx. =10-4 cm3). Fields as small as 40 V/cm are measured by spectral resolution of laser-induced fluorescence from Stark-mixed parity levels. The technique is demonstrated by excitation of the A1Pi-X1Σ+ band system of BCl, produced in an rf discharge through BCl3. The absolute measurement of sheath fields, which has been elusive, is now possible
