We report a robust technique for laser frequency stabilisation that enablesthe reproducible loading of in excess of 10$^{9}$ Yb atoms from a Zeeman slowerdirectly into a magneto-optical trap (MOT) operating on the $^{1}S_{0}\rightarrow \, ^{3}P_{1}$ transition, without the need for a first stage MOT onthe $^{1}S_{0} \rightarrow \, ^{1}P_{1}$ transition. We use a simple atomicbeam apparatus to generate narrow fluorescence signals on both the 399 nm$^{1}S_{0} \rightarrow \, ^{1}P_{1}$ transition used for the Zeeman slower andthe 556 nm $^{1}S_{0} \rightarrow \, ^{3}P_{1}$ transition. We present indetail the methods for obtaining spectra with a high signal-to-noise ratio anddemonstrate error signals suitable for robust frequency stabilisation. Finallywe demonstrate the stability and precision of our technique through sensitivemeasurements of the gravitational sag of the Yb MOT as a function of theintensity of the laser cooling beams, which are in good agreement with theory.These results will be important for efficient loading of the atoms into anoptical dipole trap.
