An optical atomic clock scheme is proposed that utilizes two lasers to establish coherent coupling between the 5s{sup 2} {sup 1}S{sub 0} ground state of {sup 88}Sr and the first excited state, 5s5p {sup 3}P{sub 0}. The coupling is mediated by the broad 5s5p {sup 1}P{sub 1} state, exploiting the phenomenon of electromagnetically induced transparency. The effective linewidth of the clock transition can be chosen at will by adjusting the laser intensity. By trapping the {sup 88}Sr atoms in an optical lattice, long interaction times with the two lasers are ensured; Doppler and recoil effects are eliminated. Based on a careful analysis of systematic errors, a clock accuracy of better than 2x10{sup -17} is expected.
