Abstract

The longest tune-out wavelength for potassium atoms, λzero=768.9701(4) nm, was measured using an atom interferometer with a large irradiance gradient supported in a multipass optical cavity. Systematic errors in λzero measurements that arise from laser light, Doppler shifts, and the Earth's rotation are described. The ratio of oscillator strengths for the potassium D2 and D1 lines inferred from this λzero measurement is ρ=fD2/fD1=2.0066(11), and the ratio of line strengths is R=SD2/SD1=1.9977(11).
