Abstract
A novel technique to measure the magnetic field strength is demonstrated, which is based on blow-off beam probing combined with Doppler-tuned laser spectroscopy. The field strength is determined from the Zeeman splitting of the LiI resonance line (670.8 nm) with good time and spatial resolutions (Δt<100 μs, Δr<5 mm). The measurable field strength is less than 1 T with an accuracy of 10%.Keywords
