Direct spectroscopy of the $^2$S$_{1/2}-^2$P$_{1/2}$ and $^2$D$_{3/2}-^2$P$_{1/2}$ transitions and observation of micromotion modulated spectra in trapped \Ca

We present an experimental scheme to perform spectroscopy of the $^{2}$ S $_{1 / 2} -^{2}$ P $_{1 / 2}$ and $^{2}$ D $_{3 / 2} -^{2}$ P $_{1 / 2}$ transitions in \Ca. By rapidly switching lasers between both transitions, we circumvent the complications of both dark resonances and Doppler heating. We apply this method to directly observe the micromotion modulated fluorescence spectra of both transitions and measure the dependence of the micromotion modulation index on the trap frequency. With a measurement time of 10 minutes, we can detect the center frequencies of both dipole transitions with a precision on the order of 200 kHz even in the presence of strong micromotion.
