Voici le premier laser CO2 continu que j’ai construit en 1975.<\/b><\/i><\/span><\/span>
\n<\/span><\/span><\/span>Ce laser ce compose de 2 tube de PYREX\u00ae de 20mm de diam\u00e8tre int\u00e9rieur et 1540mm de long.Chaque tube est pourvu d’une anode et d’une cathode aliment\u00e9 en HT 25kV DC 150mA. En s\u00e9rie se trouve des r\u00e9sistances de 100kOhm.Le couplage l\/d=116 donne un miroir de sortie de R65%. Le r\u00e9sonnateur optique est de type \u00ab\u00a0CONFOCAL\u00a0\u00bb R1+R2=L;
\nLa longueur du r\u00e9sonnateur est de 3600mm, il se compose de 2 miroirs de renvoi en CuBe dor\u00e9 R 99.5% qui sont mont\u00e9s sur un syst\u00e8me microm\u00e9trique \u00e0 45 degr\u00e9s dans la boite de renvoi qui est reli\u00e9e \u00e0 la masse du chassis.<\/span><\/span>
\n<\/span><\/span><\/span>Le miroir totalement r\u00e9flecteur est en CuBe dor\u00e9 avec un Rayon de courbure de 3500mm R99.5% et le miroir de sortie en ZnSe R 65%\/AR avec un rayon de courbure de 3500mm.
\nLe diam\u00e8tre du faisceau TEM01 est de 6.6mm la divergence du faisceau de 1.7 mrad.
\nPression de travail 16 – 24 torr
\nCourant d\u00e9charge 50 – 150mA
\nEau refroidissement 2L\/min
\nGaz\u00a0 30 L\/h<\/span><\/span> <\/span><\/p>\n<\/div><\/section><\/div>\n
