1. A system for distributing a reference timing signal comprising:
- a clock comprising;
a reference oscillator associated with the reference timing signal; and
a femtosecond laser configured to produce a femtosecond laser pulse sequence stabilized by the reference oscillator;
at least one beamsplitter configured to split the femtosecond laser pulse sequence into one or more split laser pulse sequences; and
one or more remote nodes that are spaced from the clock, and configured to generate distributed timing signals associated with the reference timing signal, based on associated ones of the one or more split laser pulse sequences.

Abstract
A system for distributing a reference oscillator signal includes a clock having a reference oscillator and a femtosecond laser stabilized by the reference oscillator. The system also includes at least one beamsplitter configured to split the femtosecond laser. The system further includes one or more remote nodes that are spaced from the clock. The remote nodes are configured to generate reference signals based on the split femtosecond laser.

11. A method for distributing a reference timing signal comprising:
-
generating, at a reference oscillator, a reference oscillation associated with the reference timing signal; producing, with a femtosecond laser, a femtosecond laser pulse sequence stabilized by the reference oscillation; splitting the femtosecond laser pulse sequence into one or more split laser pulse sequences; and generating, at one or more remote nodes spaced from the clock and associated with the one or more split laser pulse sequences, distributed timing sequences associated with the reference timing signal, based on the femtosecond laser pulse sequence. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A clock comprising:
-
a reference oscillator; a femtosecond laser configured to produce a femtosecond laser pulse sequence stabilized by the reference oscillator; and a beamsplitter in a path of the femtosecond laser pulse sequence, configured to redirect at least a portion of the femtosecond laser pulse sequence to a distribution system; wherein the distribution system comprises a transfer laser configured to produce a frequency reference that is locked to the femtosecond laser pulse sequence, and one or more beamsplitters configured to distribute the frequency reference of the transfer laser to one or more remote nodes. - View Dependent Claims (19, 20)
