Abstract:

We present and analyze a method of laser frequency stabilization via steady-state patterns of spectral holes in Eu3 Y2SiO5. Three regions of spectral holes are created, spaced in frequency by the ground state hyperfine splittings of 151Eu3 . The absorption pattern is shown not to degrade after days of laser frequency stabilization. An optical frequency comparison of a laser locked to such a steady-state spectral-hole pattern with an independent cavity-stabilized laser and a Yb optical lattice clock demonstrates a spectral-hole fractional frequency instability of 1.0 x 1015-15 tau -12 that averages to 8.5 4.8 over -1.8 x 10-17 at tau 73 s. Residual amplitude modulation at the frequency of the RF drive applied to the fiber-coupled electro-optic modulator is reduced to less than 1x10-6 fractional amplitude modulation at 1 s by an active servo. The contribution of residual amplitude modulation to the laser frequency instability is further reduced by digital division of the transmission and incident photo detector signals to less than 1 x 10-16 at tau 1 s.
