More Book Details

Description of the Book:

Progress towards the development of a laser employing fluorescent organic compounds is discussed with emphasis upon obtaining the exact composition of polymer required to achieve the desired optical properties. Dibutylphthalate (DBP) is added to the methyl methacrylate monomer in order to reduce the stress optical coefficient. The difficulties of making accurate measurements of the stress optical coefficient around the zero point are discussed. It proved impossible to measure the stress optical coefficient with sufficient accuracy. It was determined that 10% by weight DBP was approximately the right concentration for a zero stress optical coefficient. A series of polymers were prepared arranging from 9 to 11% DBP in 0.1% intervals. After annealing, those samples in the range of 10.4 to 10.6 per cent DBP were free of any birefringence with the 10.5% being the optimum concentration
