The effects of ionizing and neutron radiation on the characteristics and performance of laser diodes are reviewed, and the formation mechanisms for nonradiative recombination centers, the primary type of radiation damage in laser diodes, are discussed. Additional topics include the detrimental effects of aluminum in the active (lasing) volume, the transient effects of high-dose-rate pulses of ionizing radiation, and a summary of ways to improve the radiation hardness of laser diodes. Radiation effects on laser diodes emitting in the wavelength region around 808 nm are emphasized.

The main features in the ultraviolet spectrum of poly(methylphenylsilylene) can be interpreted as falling into four regions. These assignments of electronic transitions could be useful for the understanding of photoluminescence spectra, in increasing the efficacy of an interpreting the results of photobleaching experiments, in clarifying the mechanisms of photodegradation in poly(arylsilylene), and in the design of related new materials for specific optical applications.
