The detection and measurement of gas concentrations using the characteristic optical
absorption of the gas species is important for both understanding and monitoring a variety of …

When first tunable diode lasers were developed in the mid-1960s they found immediate
application as much needed tunable sources for high-resolution laser absorption …

We have measured the absolute optical frequency of the cesium D 1 line at 335 THz (895
nm). This frequency provides an important link for a new determination of the fine structure …

We present the analysis of the self-injection locking of a single-frequency laser diode to a
high-Q whispering gallery mode (WGM) microresonator with Rayleigh backscattering …

We have used the comb of optical frequencies emitted by a mode-locked laser as a ruler to
measure differences of as much as 20 THz between laser frequencies. This is to our …

We have developed an enhanced Littrow configuration extended cavity diode laser (ECDL)
that can be tuned without changing the direction of the output beam. The output of a …

Diode lasers are now widely used in many experiments in optical and atomic physics.
Although these devices are compact, simple, and relatively inexpensive, unmodified laser …

Today's precision experiments for timekee**, inertial sensing, and fundamental science
place strict requirements on the spectral distribution of laser frequency noise. Rubidium …

We have developed external cavity diode lasers, where the wavelength selection is assured
by a low loss interference filter instead of the common diffraction grating. The filter allows a …

We demonstrate time-resolved counting of single atoms extracted from a weakly interacting
Bose-Einstein condensate of R 87 b atoms. The atoms are detected with a high-finesse …
