Journal ArticleDOI
Phase-Coherent Optical Pulse Synthesis from Separate Femtosecond Lasers
TL;DR: A coherently synthesized optical pulse is generated from two independent mode-locked femtosecond lasers, providing a route to extend the coherent bandwidth available for ultrafast science and represents a new and flexible approach to the synthesis of coherent light.
Journal ArticleDOI
Subfemtosecond timing jitter between two independent, actively synchronized, mode-locked lasers.
Robert K. Shelton,Seth M. Foreman,Long-Sheng Ma,John L. Hall,Henry C. Kapteyn,Margaret M. Murnane,Mark Notcutt,Jun Ye +7 more
TL;DR: With the implementation of a fast-bandwidth servo, along with improved laser construction and associated better passive stability, this work has achieved subfemtosecond relative timing jitter between two independent, actively synchronized, mode-locked Ti:sapphire lasers.
Journal ArticleDOI
Sub-10-femtosecond active synchronization of two passively mode-locked Ti:sapphire oscillators
TL;DR: In this article, the authors demonstrate robust synchronization of pulse trains from two separate femtosecond lasers, with a timing jitter of,5 fs, at a bandwidth of 160 Hz, observed over several minutes.
Journal ArticleDOI
Broadband optical absorbance spectroscopy using a whispering gallery mode microsphere resonator.

TL;DR: The ability to excite and monitor many whispering gallery modes (WGMs) of a microsphere resonator simultaneously in order to make broadband optical absorbance measurements is demonstrated.
Journal ArticleDOI
Phase-coherent synthesis of optical frequencies and waveforms

TL;DR: In this article, a frequency comb (with 100 MHz spacing) spanning an entire optical octave (>300 THz) has been produced, corresponding to millions of marks on a frequency “ruler” that are stable at the Hz level.
