Alkali density in an optically pumped low pressure cell was increased from 0.5 to 85×10 12 cm −3 , resulting in a factor of 200 increase in Lorentzian width due to Stark broadening (2.76GHz/10 12 cm −3 ). The observed red shift is consistent with literature, and the shift-to-width ratio δ / γ =−0.356±0.015 informs an electron temperature of 1820±100K. A linear trend between alkali density and electron density is seen, suggesting that electron impact is the primary plasma production mechanism. A maximum ionized concentration of 28% was observed.","PeriodicalId":17280,"journal":{"name":"Journal of The Optical Society of America B-optical Physics","volume":"43 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135111553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coherent detection of such structured modes can be difficult given their structural complexity and the deterioration of the quality of modes during propagation in turbulent environments. In this paper, we first study the detection of RC modes by using fork-shaped diffraction gratings and then propose an incoherent detection approach to classify 16 classes of RC modes based on training a convolutional neural network model using DenseNet-201 architecture. The dataset comprises recorded images of RC modes after a 120 cm propagation length in a turbulent underwater environment. As the evaluations indicate, the classifier has an accuracy of 98% in identifying RC modes measured in moderate turbulence with a strength level of C n 2 ∼10 −12 m −2/3 . This method eliminates the difficulties caused by the use of multiple optical elements in coherent detection techniques such as diffraction gratings. Besides simplifying the optical system settings, it also reduces the volume and cost of implementation, especially in optical communication applications.","PeriodicalId":17280,"journal":{"name":"Journal of The Optical Society of America B-optical Physics","volume":"296 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136019108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rodríguez","doi":"10.1364/josab.502568","DOIUrl":"https://doi.org/10.1364/josab.502568","url":null,"abstract":"The semiclassical expressions for susceptibilities are inadequate when quantum aspects of light become prominent. A more appropriate formulation of the electrical susceptibility theory requires the quantization of the electromagnetic field. We show here a way to do this up to the second order, within a low-dimensional system. The generalized expressions reveal that susceptibilities depend on the quantum state of light. As experimentally verifiable consequences of this, we predict new phenomena such as photon number-dependent refractive index, even in the linear regime, and non-quadratic second harmonic generation, which should be appreciable when very low-intensity coherent light is involved. We also deduce when the semiclassical expressions, which happen to be particular cases of those derived here, can be used confidently.","PeriodicalId":17280,"journal":{"name":"Journal of The Optical Society of America B-optical Physics","volume":"330 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136018111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
