Low-noise simultaneous fluorescence detection of two atomic states.

چکیده
We demonstrate a new simultaneous normalized detection technique for fluorescence detection of ultracold atoms in a superposition of ground-state hyperfine levels. Using this technique we observe atom shot-noise limited detection signal-to-noise ratios in excess of 7800:1 per shot and 14400:1 in 1 s.

Transient state monitoring by total internal reflection fluorescence microscopy.
Triplet, photo-oxidized and other photoinduced, long-lived states of fluorophores are sensitive to the local environment and thus attractive for microenvironmental imaging purposes. In this work, we introduce an approach where these states are monitored in a total internal reflection (TIR) fluorescence microscope, via the characteristic variations of the time-averaged fluorescence occurring in ...
متن کاملTwo-line atomic fluorescence flame thermometry using diode lasers
This paper reports on the first application of diode laser based LIF for pointwise temperature measurements in flames. The technique is based on two-line atomic fluorescence (TLAF) thermometry of indium atoms seeded at trace levels into the flame. Two novel extended cavity diode laser systems (ECDLs) were developed, providing tunable single-mode radiation around 410 and 451 nm, respectively, to...
متن کاملDual role of CdSe quantum dots for simultaneous separation and spectrofluorimetric ultrasensitive determination of heparin
The present study offers a new method based on CdSe quantum dots (QDs) for simultaneous separation and determination of trace levels of heparin (Hep) in human serum samples. In this technique, CdSe QDs perform two different functions in Hep analysis process. Mercaptoacetic acid-capped red CdSe QDs (λex=690 nm) are conjugated to Hep and the Hep-QD conjugation is then used as an extraction...

متن کاملPhased array ultrasonic imaging using an improved beamforming based total focusing method for non destructive test
One of the novel ultrasonic phased array based scanning methods for ultrasonic imaging in non-destructive test is total focusing method (TFM). This method employs maximum available information of the phased array elements and leads to an improved defect detection accuracy compared to conventional scanning methods. Despite its high detection accuracy, TFM behaves weak in distinguishing the real ...
