These lasers deliver 25–35 fs laser pulse time duration, from 1 mJ up to 5 J energy per pulse, high repetition rate from 10 Hz to 5 kHz, and up to 200 TW of instantaneous power or 50 W of average power. The aim of this facility is, first to produce laser based radiation source ranging from THz up to the hard x-ray and acceleration of high energy particles; second to develop and optimize such laser based sources and study their potential applications in field such as biomedical imaging, time resolved x-ray spectroscopy or molecular imaging.

Owing to high angular/spectral selectivity of the Bragg grating monochromators can be realised without application of input/output slits. Strengthening of an spectral dispersion due to the 3D-diffraction provides a single-mode oscillation in dye lasers even with nanosecond pumping. The polychromator with a such grating is attained in divergent “white” light beam in a plane of a grating dispersion. Two diffracted beams controlled power on a grating exit in a combination with the simple lens optics for beam crossing implement a 2-beam interferometer with controlled spatial resolution. Calibrated on a spatial frequency the grating on a goniometric knot forms the high-precision wavelengthmeter. High angular selectivity of such grating allows to implement optical vibration sensor with sensitivity comparable with that at modern seismographer.","PeriodicalId":254986,"journal":{"name":"2010 International Conference on Advanced Optoelectronics and Lasers","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114840648","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}
