Optical gas sensing: a review

J Hodgkinson, RP Tatam - Measurement science and technology, 2012 - iopscience.iop.org
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 …

A review of recent advances in semiconductor laser based gas monitors

P Werle - Spectrochimica Acta Part A: Molecular and …, 1998 - Elsevier
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 …

Self-injection locking of a laser diode to a high-Q WGM microresonator

NM Kondratiev, VE Lobanov, AV Cherenkov… - Optics …, 2017 - opg.optica.org

Absolute Optical Frequency Measurement of the Cesium Line with a Mode-Locked Laser

T Udem, J Reichert, R Holzwarth, TW Hänsch - Physical review letters, 1999 - APS
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 …

Accurate measurement of large optical frequency differences with a mode-locked laser

T Udem, J Reichert, R Holzwarth, TW Hänsch - Optics letters, 1999 - opg.optica.org
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 …

Littrow configuration tunable external cavity diode laser with fixed direction output beam

CJ Hawthorn, KP Weber, RE Scholten - Review of scientific instruments, 2001 - pubs.aip.org
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 …

A simple extended-cavity diode laser

AS Arnold, JS Wilson, MG Boshier - Review of Scientific Instruments, 1998 - pubs.aip.org
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 …

Interference-filter-stabilized external-cavity diode lasers

X Baillard, A Gauguet, S Bize, P Lemonde… - Optics …, 2006 - Elsevier
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 …

Coherent transfer of photoassociated molecules into the rovibrational ground state

K Aikawa, D Akamatsu, M Hayashi, K Oasa… - Physical review …, 2010 - APS
We report on the direct conversion of laser-cooled K 41 and Rb 87 atoms into ultracold K 41
Rb 87 molecules in the rovibrational ground state via photoassociation followed by …

Correlations and counting statistics of an atom laser

A Öttl, S Ritter, M Köhl, T Esslinger - Physical Review Letters, 2005 - APS
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 …
