Isotope shifts between the stable isotopes of calcium have been measured in the transition 4s<sup>2</sup> <sup>1</sup>S<sub>0</sub>-4s5s <sup>1</sup>S<sub>0</sub> by the method of two-photon laser spectroscopy. The relative positions of the isotopes are (in MHz): <sup>40</sup>Ca, 0.00(27); <sup>42</sup>Ca, 606.33(7); <sup>43</sup>Ca, 906.32(5); <sup>44</sup>Ca, 1169.99(4); <sup>46</sup>Ca, 1704.33(70); <sup>48</sup>Ca, 2193.49(5).
