The first imaging spectrometer is intended mostly for astronomical observations and studying the planets and emission objects: planetary nebulae and Seyfert galaxies. The spectrometer is based on the tunable TeO2 acousto-optical filter that combines simultaneously both high spatial resolution and high spectral resolution. The acousto-optical filter with a 13 Å pass band at wavelength 6328 Å operates in the wavelength range 6300-11000 Å. The spatial resolution of the spectrometer is about 1 angular sec. The geometry of acousto-optical interaction as well as design peculiarities of the acousto-optical filter is discussed. The astronomical observations were performed at the Crimea laboratory of Sternberg Astronomical Institute. The telescope was 600 mm f/12.5 Cassegraine Zeiss-600. Series of spectral images of the planetary nebulae NGC 7027 in the vicinity of the 6563 Å Hα and 6586 Α N [II]emitting lines are obtained. The performed measurements of the rapid spectral variability of Hαemission line in the nuclear of the Seyfert galaxy NGC 4151 (redshift Z=0.003) are also discussed. In this paper we describe also the laboratory visible - to - near infrared acousto-optical spectral imager. TeO2 based acousto-optical filter with 15Å pass band and tuning wavelength range 6000 - 1400 Å is used in this imager. Image - forming optics, RF electronics and factors influencing on the image quality is discussed.","PeriodicalId":405317,"journal":{"name":"Acousto-Optics and Applications","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114947744","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}

These anticipations were confirmed experimentally 10 years later. In the following years the influence of elastic wave on light wave propagation was described from many points of view, examined experimentally, and applied in practice. The first works describe interaction of unlimited plane waves but the fundamental meaning for practical applications has the description of real wave beams’ interaction. This problem still exists despite huge progress made in acoustooptical phenomenon’s investigations. Among numerous description methods applicable to various, specific acoustooptical interactions are also such ones, that make it possible to describe interaction of beams of arbitrary spatial distributions. However, in today’s applications of acoustooptical phenomenon such as modulators, filters, spectrum analyzers, etc. one uses mostly laser light. Light beams emitted by laser may in many cases be described as gaussian beams. It means, that the correct description of acoustooptical interaction involving optical gaussian beams has significant practical meaning. This paper presents the review of theoretical works describing acoustooptical interaction between optical gaussian beams and acoustical waves. Special attention has been paid the application of complex geometrical optics’ methods.","PeriodicalId":405317,"journal":{"name":"Acousto-Optics and Applications","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132366226","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}

The power delivered to the pulsed gas laser changes the pressure (and temperature) of the laser medium. The monitoring of the acoustic wave in the laser cavity, taken as a specific acoustic resonator, can be an easy measure of the local changes of the laser gas pressure. The changes of the pressure involve changes of the laser gas density, and changes of the refractive index, as a consequence. It leads to a frequency tuning of the laser optical resonator. In the case of the CO2 laser a rotational line hopping phenomenon is observed as a result. In other words, a single frequency operation of the RF excited CO2 laser with a pulsed plasma is problematic. The main goal of the experiment is to give a picture of the laser plasma behavior during the pulsed excitation of the CO2 laser medium.","PeriodicalId":405317,"journal":{"name":"Acousto-Optics and Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125675499","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}
