Laser Nowadays lasers can be applied in most branches of activity (industry,medical, nuclear, military, household electrical appliances…). Optis has developed many software and applications specific to lasers : • laser servo-control system for ultraviolet line • laser scanning system for tri-dimensional measuring • laser scanner for 3D modelling of teeth • laser diode optical connector/ optical fibre • laser beam transport • laser gap study for surgical laser in ophthalmology • impulse space and temporal analyse stretching software • multimode propagation simulation in an opto-mechanical environment • laser diffraction simulation by small apertures or lens grating simulation laser cutting REFERENCES CEA • AUTOMATECH • PRIMA INDUSTRIE ENSTA • DGA • LOA • CELIA
