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 …

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 …

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 …

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 …

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 …

1.1. Background This article reports work carried out under the auspices of the Committee
on Data for Science and Technology (CODATA) Task Group on Fundamental Constants. 1 It …

We have used the frequency comb generated by a femtosecond mode-locked laser and
broadened to more than an optical octave in a photonic crystal fiber to realize a frequency …

1.1. Background This paper gives the complete 2006 CODATA self-consistent set of
recommended values of the fundamental physical constants and describes in detail the …

We demonstrate a great simplification in the long-standing problem of measuring optical
frequencies in terms of the cesium primary standard. An air-silica microstructure optical fiber …
