Abstract We report on our system and scheme for single‐ion spectroscopy of the2S 1 / 2 ( F = 0 ) −2D 3 / 2 ( F = 2 ) clock transition in 171 Yb + . Spectroscopy of the clock transition requires decoupling of the2D 3 / 2 ( F = 2 ) state from the laser cooling cycle. We investigate this decoupling of the2D 3 / 2 ( F = 2 ) state by using independent light sources for driving of all the transitions between the hyperfine structures contained in the cooling and repumping transitions. We observe the carrier spectrum of them F = 0 − mF ′= 0 magnetic‐insensitive transition with a spectral width of 380 Hz.
