Our model accounts for laser power output, the length of the optical fiber guide, its absorption, the Rayleigh and Brillouin scattering in the optical fiber guide, and the photo detector parameters. The scattering properties of the moving particles in the liquid or gas flow which is accessed by the LDV are accounted for by an integral scattering coefficient. We show that the Rayleigh and Brillouin scattering in the optical fiber are the principal noise sources that corrupt the signal-to-noise ratio of the present LDV. The numerical examples show that Ae SNR can be as low as 0 dB in the case of the typical optical fibers of a length of several kilometers","PeriodicalId":370622,"journal":{"name":"2006 International Workshop on Laser and Fiber-Optical Networks Modeling","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117184814","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}

Gas lasers have good characteristics, but they rather bulky and power-intensive, therefore the problem of replacement of gas lasers semi-conductor lasers is very actual now. The western researchers have already a number of experiments and have established lines of absorption in pairs iodine in a range of lengths of waves from 500 nanometers up to 1300 nanometers. From this file of lines of absorption of us interest three lines of absorption on 502 nanometers, 633 nanometers, 793 nanometers which will allow to block all seen range. There is a problem of creation of the stabilized semi-conductor laser source with the high characteristics, overlapping the above-stated lengths of waves. Creation of the semi-conductor lasers stabilized on frequency opens ample opportunities in measuring interferometry. In the report the opportunity of use of serially let out semi-conductor lasers is discussed, at creation stabilized on superthin lines of absorption in iodine of lasers. In the report it is offered and use is argued as fundamental system of lengths of waves (or sources of radiation) lines of radiation of 502 nanometers, 633 nanometers, 793 nanometers.

If even the perfect stabilized lasers are used, the accuracy of interference measurements can be aggravated by few orders because of a rather weak optical feedback. The new principle of extra-resonator heterodyne interferometry based on a laser frequency modulation (FM) of light that overcomes this difficulty is described. The multi-mirror cavity model of precise laser device is used to estimate the effect of the performance degradation both in the long-path geophysical laser strainmeters and in the equal-arm gravitational wave interferometers.
