We observed a clear-cut reduction in the growth of plants. The fluorescence spectra of green maize leaf induced by 337 nm radiation were obtained in each case, consisting of four peak bands at 435 nm (F435), 525 nm (F525), 684 nm (F684) and 740 nm (F740), respectively.

The tangential phase-matching (TPM) anisotropic interaction can greatly reduce the phase-grating intermodulations. We consider the two operating modes, high or low frequency, for the slow shear wave propagating in paratellurite with an angular tilt from the [110] axis. As two different angles lead to the same central operating frequency, we show that the low-frequency configuration allows one to greatly increase the dynamic range, compared with that obtained in the high-frequency mode. For experimental validation, two bifrequency acousto-optic modulators have been realized and tested. For a central frequency in the low-frequency configuration and a diffraction efficiency , the dynamic range is shown to be enhanced by 5 dB.","PeriodicalId":20787,"journal":{"name":"Pure and Applied Optics: Journal of The European Optical Society Part A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1998-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86126691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
