Popis:	A system is described for the absolute frequency measurement of a laser source at 445 THz probing a narrow resonance of a trapped single ion of strontium. The 474-THz frequency from a laser referenced to an iodinestabilized helium-neon laser and a known 29-THz frequency from a saturation-stabilized carbon dioxide laser are mixed in an AgGaS(2) nonlinear crystal to synthesize the 445-THz radiation. A preliminary measurement of the (88)Sr(+) 5s(2)S(1/2)-4d(2)D(5/2) center frequency yielded a frequency of 444779044.14 +/- 0.39 MHz (1sigma).
