Ultrafast fibre lasers are fundamental building blocks of many photonic systems used in
industrial and medical applications as well as for scientific research. Here, we review the …

We review experimental progress on optical atomic clocks and frequency transfer, and
consider the prospects of using these technologies for geodetic measurements. Today …

Most mode-locking techniques introduced in the past, focused mainly on increasing the
spectral bandwidth to achieve ultrashort, sub-picosecond-long coherent light pulses. By …

A list of standard reference frequency values (LoF) of quantum transitions from the
microwave to the optical regime has been recommended by the International Committee for …

We report on a novel architecture for robust mode-locked femtosecond fiber lasers using a
nonlinear optical loop mirror with all polarization-maintaining fibers. Due to a nonreciprocal …

Extremely narrow optical resonances in cold atoms or single trapped ions can be measured
with high resolution. A laser locked to such a narrow optical resonance could serve as a …

This paper gives the 1998 self-consistent set of values of the basic constants and conversion
factors of physics and chemistry recommended by the Committee on Data for Science and …

Optical frequency combs,, provide equidistant frequency markers in the infrared, visible and
ultraviolet,, and can be used to link an unknown optical frequency to a radio or microwave …

The rise time of intense radiation determines the maximum field strength atoms can be
exposed to before their polarizability dramatically drops due to the detachment of an outer …

We stabilized the carrier-envelope phase of the pulses emitted by a femtosecond mode-
locked laser by using the powerful tools of frequency-domain laser stabilization. We …
