All of proposed measurement techniques use one of the Kerr-related phenomena, which are self-phase modulation, modulation instability, cross-phase modulation or four-wave mixing. Some of the methods applied to determine the nonlinear coefficient are based on pulsed lasers instead of continuous wave sources. The brief description of each measurement scheme and method is given. This paper focuses on the comparison of different noninterferometric measurement schemes in terms of their construction set-up simplicity, equipment cost, measurement time and field usage. In many of the measurement techniques, presented in this paper, the accurate determination of the input power becomes a critical factor to reduce the measurement uncertainty. Versatility of testing the various types and lengths of fibers is also an important issue in the design of optical devices and systems.","PeriodicalId":300417,"journal":{"name":"Advanced Optoelectronics and Lasers","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127795838","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}

We propose time-multiplexing, where several pulsed laser diode beams are guided onto a common optical path. This allows to superpose the power of the diodes while maintaining the beam parameter product of a single laser diode. Pulsed operation of continuous wave laser diodes was shown to be possible up to pulse enhancement factors of ten provided that pulse duration is <300 ns. We use a fast digital optical multiplexer built up by a cascade of binary optical switches. For the latter we use a polarisation switch (voltage-driven LiNbO3-crystal) followed by a polarisation filter, which allows addressing of two optical paths. Instead of direct on/off-switching we drive the crystals with a harmonic voltage course to avoid ringing caused by piezo-electricity. Up to now an optical power of 10.5 W was generated, 13 W are expected with some improvements. With the use of new 8W laser diodes even the generation of 25 W will be possible.","PeriodicalId":300417,"journal":{"name":"Advanced Optoelectronics and Lasers","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123265267","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}
