FROM THE LOCAL COORDINATOR'S DESKThe Workshop, which is third of its kind as an activity of the office ofExternal Activities of International Centre for Theoretical Physics, aimsat exposing the participants to current activities and future prospectsof Optical Physics in both pure and applied research as well as indevelopment projects. Each subject will begin with an introduction andgradually proceed towards advanced topics for solving problemsrelevant to research and development. Afternoon sessions will bedevoted to discussions and seminars.The Workshop would exhibit some basic experimental set-up with theview to exposing students of high schools of science, technology,mathematics (STMC) to the practicality of the use of Lasers on theContinent.WORKSHOPThe main topics to be treated include:Basic in lasers, geometrical, physical and quantum opticsOptical techniques for research, education anddevelopment in Africa;Application of Lasers in Optical Fibre Communication.Environmental Studies. Biomedicine, Chemistry.Agriculture. Engineering, Industry.The Workshop aims at promoting closer links in optics and lasersamong scientific institutions, industries and the African LAM Networkby:Providing a forum for enhancing exchange of ideas amongAfrican scientists and scientists from other parts of theworld;Encouraging International Commission for Optics (ICO), aswell as other international Scientific organisations, toassist in the development and training of young scientistsin optical and laser science.A round table discussion on laser and optics for development will beorganised.The general outlook of our programmes conform with the activities ofthe African Laser Atomic and Molecular Network. The workshop aims

at encouraging African Scientists to project their work in Lasers whichis composed of areas such asAREAEnvironmentMetrologyLasersOptical SpectroscopyFibre OpticsMedicineChemistryNO. OF PAPERS5107521131A total of 31 papers on Lasers and optical fibres to be presented at thisworkshop are of much relevance to our national development.We are most grateful for the immense response by 150 applicants fromall over the continent out of which only 35 were i ivited due to financialconstraints on the workshop budget. We hope this will not deterAfrican scientists in showing interest in this new field of research inthe next workshop.Local Organiser
