We report the efficient operation of a continuous-wave, single-frequency, diode-pumped Nd:FAP laser at 1.126 μm. When frequency quadrupled, such a laser might be used as a local oscillator for an optical frequency standard based on the single-photon 2S1/22D5/2 electric quadrupole transition of a trapped and laser-cooled 199Hg+ ion. Since the frequencies of the atomic transition and the laser are harmonically related, this scheme helps to simplify the measurement of the SD clock transition frequency by a phase-coherent chain to the cesium primary frequency standard.
