A mid-infrared frequency reference for synchonized octave-spanning non-linear dynamics
Abstract
A mid-infrared frequency reference for synchonized octave-spanning non-linear dynamics: The requested instrument is an Aculight Argo"s 2400-SF mid-infrared degenerate opticalparametric oscillator, paired with the Yokogawa mid-infrared spectrum analyser AQ6375B, as"the narrowest linewidth high-power mid-infrared pump laser to date. The Aculight Argos opticalparametric oscillator achieves up to" 3W of continuously tunable idler output at roomtemperature, with wavelength from 2.2-~m to 4.6-~m, while preserving a coherence li"newidthapproximately 500 kHz. The parametric oscillator also simultaneously produces up to 5W signaloutput from 1.4-~m to 2.0-~m f"or coherent nonlinear wave-mixing. Complementarily on thedetection side, the Yokogawa AQ6375B is the only mid-infrared optical spec""trum analyzer todetect the frequency modes in high spectral resolution (50 pm) and high sensitivity (down to -70dBm), with the 55"" dB dynamic range and fast scanning in order to observe the high-densitynonlinear modal interactions, soliton dynamics and frequenc""y mixing. When referenced againstour 1-Hz carrier-envelope-offset-stabilized Menlo frequency comb at UCLA, the mid-infraredfrequen"cy uncertainty can be measured with a frequency spacing imprecision of 1 part in 1017and an absolute frequency instability of 1 part in 1015 or better. This instrumentation allows us to achieve and examine synchronized chip-scale nonlinearoscillators spanning" up to a complete octave or more. The nonlinear frequency modes cover upto more than 3,600 phase-locked and mode-locked eigenstates"", advancing key Navy and DoDtechnology areas in mid-infrared sensing, RF communications and electronic warfarecapabilities. The re""quested frequency standard is critical to our next-frontier nonlinear dynamicsresearch and research-related education, enabling cor"e capabilities in three major focus areas: (1)synchronization of nonlinear oscillators spanning up to an octave or more (Section 2.1); (2)enhanced dynamical nonlinearities in the mid-infrared (Section 2.2); and (3) a Menlo combstabilized 2.3-~m frequency reference for Navy and DoD capabilities (Section 2.3). This willserve as the first and only continuous-wave mid-infrared (2.2-~m to 4.6-~"m) laser source athigh-power in a university for the Los Angeles, San Diego and Santa Barbara greatermetropolitan areas.The reque""sted instrument budget is $180,000 and will be matched with $17,744 fromstart-up funds of the investigator. The instrument will be"" phase-locked to the complementaryfrequency comb and ultrastable laser (1-Hz linewidth and sub-100-kHz drift over 1-day;$350,000)"" at UCLA, to achieve the DoD mid-infrared frequency standard. The precision andstable metrology enables between two-orders to six-o""rders of magnitude improvement offrequency (and timing) characterization over the best fiber-laser optical interferometers, enablin""gthe understanding of the noise-seeding, precision dispersive nature, and chaos generation ofhigh-dimensional nonlinear oscillator"s.
