Research & Develop Of Computer Controlled Wide Band-tunable Laser

In the paper, we had studied with theory and experiment in three aspects as below, and researched and developed two testing laser system.Optical Section:(1)have been constructing optical system;(2)have been researching the properties of parameter oscillator;(3)with experimental antithesis, have been optimizing the optical component.Mechanical Section:(1)have been designing and machining a compact! integrative optical pedestal;(2)have been designing and machining mechanical components and optical accessories.Controlled Section:(1)have been constructing local measure and feedback system controlled by single chip;(2)have been researching and developing remote measure! control software drived by computer.Testing Laser System up to par:(1)41 Onm to 71 Onm wide band-tunable spectrum range;(2)non-stability tess than 3 percent;(3)single pulse energy threshold under 12 mj;(4)crystal efficiency more than 20 percent;(5)the maximal output power more than 1MW;(6)external form size: 380x260x265mm3 [compact type I], 800x400x200mm3 [integrative type II including pump source and parameter oscillating system];(7)local operation controlled by single chip panel;(8)remote operation executed by Windows 9x software.
