The simulation results show that, the characteristics of limiting power and pulse shape are controlled mainly by focal length when other parameters are fixed. When focal length is short, for example 5cm, the characteristic of limiting power and pulse shape is close to ideal. In experiment, focusing 8ns, 1064nm, 16mJ pulses into CCl4 medium, the rules of limiting power and pulse shape versus focal length are investigated.

According to the measurement results of Al2O3/ZnO films' resistivity and UV-Visible transmission spectra, the lowest resistivity of 0.0048Ωcm and optical transmission of larger than 80% were obtained for these Al2O3/ZnO films in this paper. After treated up to 720h under harsh environmental condition with relative humidity of 85°C and temperature of 80°C, these samples conductivity degradation is in the range of 12%~14% for Al2O3/ZnO films, which indicates that the Al2O3/ZnO films have better stability compared to ZnO films.","PeriodicalId":155352,"journal":{"name":"2010 Symposium on Photonics and Optoelectronics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127003739","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}

They have been used in a wide variety of spectrograph and synchrotron radiation facilities. In recent years, a new fiber optic position sensor based on holographic variable line space plane grating is developed. In this paper, we briefly describe the theoretical background to the position sensor. In order to improve the performance of the position sensor, it's necessary to study the diffraction spectrum of the variable line space grating. Based on the Fraunhofer formula for light wave scalar diffraction theory, the diffraction spectrum of the variable line space grating thus obtained is very different from that of the classical grating. The genetic algorithm is introduced to the period distribution optimization of variable line space grating. In consideration of the computational efficiency and complexity, we assume that the single wavelength incident in parallel and uniform, and use serial discrete diffraction areas in our study. The results obtained reveals that the diffraction spectrum of the variable line space grating has a relatively strong dependency upon the grating period distribution expression, the wavelength and the incident light spot size.","PeriodicalId":155352,"journal":{"name":"2010 Symposium on Photonics and Optoelectronics","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129105995","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}
