Frequency, intensity, and field fluctuations in laser oscillators

High Frequency Intensity Fluctuations

Intensity fluctuations were measured during August 2002 near San Diego using 20 and 40 kHz cw and fm signals. Source-receiver separation was 1km; source depths were 10m to 67m; receiver hydrophone depths were 44m to 217m. A 15-element chain of CTD sensors was towed to measure horizontal temperature and salinity with 1m resolution. Comparing the spectra of the acoustic intensity fluctuations and...

Laser with thresholdless intensity fluctuations

We have studied the quantum-noise properties of a small slow-inversion laser experimentally and theoretically. As a function of pump rate, the average output intensity shows a sharp threshold, but the intensity fluctuations do not. Under quite generic conditions the intensity fluctuations of a sufficiently small slowinversion laser show highly super-Poissonian statistics ~even two times above t...

Influence of Frequency Distribution on Intensity Fluctuations of Noise

This article introduces mathematical parameters that generalize the frequency distribution of the statistical and spectral model. We show experiments that determine the influence of these parameters on the intensity fluctuations of the synthesized noise, accordingly to the theory developed by psycho-acoustic works. The main goal of these experiments is to be able to analyse and synthesize bands...

: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type

abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
