Summary

We demonstrate strong phase correlation in ultrafast mode-locking of a Ti:sapphire comb. This quantum noise correlation extends over a full optical octave, significantly below theoretical predictions.

Area of Science:

  • Physics
  • Quantum Optics
  • Laser Science

Background:

  • Ultrafast mode-locking is crucial for generating optical frequency combs.
  • Phase coherence is a key parameter determining the performance of optical frequency combs.
  • Previous predictions suggested higher quantum-limited linewidths for individual comb modes.

Purpose of the Study:

  • To investigate and establish new limits on the phase coherence of ultrafast mode-locking.
  • To determine the extent of optical phase correlation across an octave-spanning Ti:sapphire comb.
  • To compare experimental findings with theoretical predictions for quantum-limited linewidths.

Main Methods:

  • Utilized an octave-spanning Ti:sapphire laser system.
  • Employed techniques to measure the relative linewidth of comb modes.
  • Analyzed the phase correlation across a broad spectral range.

Main Results:

  • Established new, stringent limits on the phase coherence of the mode-locking process.
  • Demonstrated optical phase correlation across a full optical octave with a relative linewidth below 2.5 microHertz.
  • Observed phase correlation significantly exceeding expectations based on quantum-limited predictions.

Conclusions:

  • The mode-locking mechanism effectively correlates optical phase across the entire octave.
  • Quantum noise is strongly correlated across the comb spectrum by the mode-locking process.
  • Experimental results verify the robust phase correlation, surpassing theoretical quantum limits.
