The shortest pulses periodically emitted directly from a mode-locked Ti: sapphire laser are
approaching the two-optical-cycle range. In this region, the phase of the optical carrier with …

New methods have recently been developed to measure the carrier-envelope phase
evolution of ultrashort optical pulses. These methods utilize a powerful combination of time …

The merging of continuous wave laser-based precision optical-frequency metrology with
mode-locked ultrafast lasers has led to precision control of the visible and near-infrared …

We analyze and stabilize fluctuations of the relative phase between the carrier and the
envelope of a mode-locked laser. Mechanisms generating fluctuations of the carrier …

Recently there has been a remarkable synergy between the technologies of precision laser
stabilization and mode-locked ultrafast lasers. This has resulted in control of the frequency …

Carrier-envelope phase stabilization, has opened an avenue towards achieving frequency
metrology with unprecedented precision, and optical pulse generation on the previously …

We present an octave-spanning Ti: sapphire oscillator supporting Fourier-limited pulses as
short as 3.7 fs. This laser system can be directly CEO-phase stabilized delivering an …

We independently phase lock the repetition rates of two femtosecond lasers at their≈
456,000 th harmonic to a common optical oscillator. The timing jitter of each individual laser …

We demonstrate that the stability of the current optical frequency comb generated by a Kerr-
lens mode-locked femtosecond laser is limited by the microwave reference used for phase …

The repetition rate and carrier-envelope phase offset frequencies of a turnkey, all-fiber-
based continuum generator were phase locked to a hydrogen maser. The frequency of the …
