Active media for tunable blue–green lasers based on aminocoumarins in polymethylmethacrylate
The lasing characteristics of 17 aminocoumarins in solutions and polymer polymethylmethacrylate (PMMA) matrix pumped by exciplex XeCl-laser radiation (λpump=308 nm) are investigated. It is demonstrated that 4-CF3

Hf-radiowave specific second-order sea-surface-scattering cross-section matrix
The modified small-perturbation method is employed to derive analytic formulas for the hf-radiowave specific sea-surface second-order scattering cross section (SSC) matrix for an arbitrary scattering geometry....
