Abstract

We present a transportable effusive atomic beam apparatus for cascaded two-photon spectroscopy of the dipole-forbidden transition (6s² ¹S₀↔ 6s7s ¹S₀) of Yb atoms. An ohmic-heating effusive oven is designed to have a reservoir volume of 1.6 cm³ and a high degree of atomic beam collimation angle of 30 mrad. The new atomic beam apparatus allows us to detect the spontaneously cascaded two-photons from the 6s7s¹S₀ state via the intercombination 6s6p³P₁ state with a high signal-to-noise ratio even at the temperature of 340 °C. This is made possible in our apparatus because of the enhanced atomic beam flux and superior detection solid angle.
