“…The resonator that was proposed is called helix resonator, since it makes use of a helical slope on an annular mirror in order to achieve an unstable resonator in the azimuthal direction. For more details on the helix resonator see [11]. A first prototype of a RF excited diffusion cooled CO 2 laser with coaxial discharge geometry (short: coax laser) was completed in 1993.…”

Publication of record for individual papers is online in the SPIE Digital Library. SPIEDigitalLibrary.orgPaper Numbering: Proceedings of SPIE follow an e-First publication model, with papers published first online and then in print and on CD-ROM. Papers are published as they are submitted and meet publication criteria. A unique, consistent, permanent citation identifier (CID) number is assigned to each article at the time of the first publication. Utilization of CIDs allows articles to be fully citable as soon they are published online, and connects the same identifier to all online, print, and electronic versions of the publication. SPIE uses a six-digit CID article numbering system in which:The first four digits correspond to the SPIE volume number. The last two digits indicate publication order within the volume using a Base 36 numbering system employing both numerals and letters. These two-number sets start with 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B … 0Z, followed by 10-1Z, 20-2Z, etc. The CID number appears on each page of the manuscript. The complete citation is used on the first page, and an abbreviated version on subsequent pages. Numbers in the index correspond to the last two digits of the six-digit CID number.Downloaded From: https://www.spiedigitallibrary.org/conference-proceedings-of-spie on 05 Jul 2020 Terms of Use: https://www.spiedigitallibrary.org/terms-of-use

“…Experimental investigations of discharge excitation and optical resonators for the annular gain medium have been actively studied. [3][4][5][6][7] Such annular gain geometries are of very interest in terms of focusing beam properties as well as design considerations of discharge devices. Recently, generation of the annular shaped beams with desirable polarizations have been widely investigated.…”

We study the noncommutative superspace of arbitrary dimensions in a systematic way. Superfield theories on a noncommutative superspace can be formulated in two folds, through the star product formalism and in terms of the supermatrices. We elaborate the duality between them by constructing the isomorphism explicitly and relating the superspace integrations of the star product lagrangian or the superpotential to the traces of the supermatrices. We show there exists an interesting fine tuned commutative limit where the duality can be still maintained. Namely on the commutative superspace too, there exists a supermatrix model description for the superfield theory. We interpret the result in the context of the wave particle duality. The dual particles for the superfields in even and odd spacetime dimensions are D-instantons and D0-branes respectively to be consistent with the T-duality.
