This material has the advantage of very fast response time and fairly small absorption loss. Nonlinear optical measurements have been performed for various sample forms, single crystals1) solvent-cast films, Langumuir-Blodgett (LB) films2), and vacuum-deposited films3),4). Among these, vacuum-deposited films are easiest to prepare because the process is dry and not time-consuming. However, the measured χ(3) values for films deposited by the usual method were not so large (≃ 1 × 10−11 esu) compared with those of single crystals1) and LB films2). This paper reports on the fairly large χ(3) value that has been observed in a highly-oriented epitaxial PDA thin film prepared by a successful vacuum-deposition method. This χ(3) value is larger than LB films and comparable to that of single crystals. To properly evaluate the χ(3) value, a third-harmonic generation (THG) measurement system with high accuracy has been set up.","PeriodicalId":208307,"journal":{"name":"Nonlinear Optical Properties of Materials","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127173279","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}

Changes in the environmental conditions, such as protonation or de-protonation or addition of nonlinear inactive, however highly polarizing molecules to the species under consideration may influence the nonlinearities in quite different ways. Protonation, as the first example, can enhance or decrease the nonlinearity by producing a new chemical species upon inclusion of a proton in the original structure. An increasing rate of protonation will result in the production of more and more molecules of this new subspecies in the monolayer, an effect that can be conveniently monitored by the concomitant changes in linear optical absorption. Alternatively, we would like to show that changes in the environmental symmetry of a monolayer induce a strong nonlinear polarization which is not present in the isolated organic molecule.","PeriodicalId":208307,"journal":{"name":"Nonlinear Optical Properties of Materials","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128476609","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}
