Abstract
A compact optical clock and frequency comb system is presented, based on a octave-spanning Ti:sapphire laser referenced to the optical transition in methane at . The reference methane transition is accessed by a stabilized HeNe laser in a compact transportable format. The output from the octave-spanning Ti:sapphire laser is used to generate a mid-IR comb at the reference wavelength . Direct comparison of the stabilized optical frequency comb with an ultralow expansion glass cavity-stabilized diode laser at shows an Allan deviation of the frequency comb of in .
