The modulation transfer function of a type II superlattice focal plane array is characterized, and discrepancies from the predicted results are analyzed.
Self-guided high-intensity filaments generated by ultrashort laser pulses can initiate water condensation and aerosol particle growth, even at less than 100% relative humidity.
The cost and availability of these important materials have had their ups and downs. The optics industry is using several strategies to make sure future needs are met.
