Nonlinear Optical Investigation of Microbial Chromoproteins [PDF]
Membrane-bound or cytosolic light-sensitive proteins, playing a crucial role in energy- and signal-transduction processes of various photosynthetic microorganisms, have been optimized for sensing or harvesting light by myriads of years of evolution. Upon

Optically Quiet Quasars – Radio and Optical Investigations [PDF]
The activity in the nuclei of bright galaxies could arise from a number of sources: they may contain compact variable radio sources, they may be strong IR/optical/X–ray continuum sources, or they may have strong emission lines. Usually but not always these properties go together as in radio loud quasars.

Ultrasonographic investigation of optic neuritis [PDF]
A pilot echographic study was conducted to determine the incidence and severity of optic nerve swelling in acute 'idiopathic' optic neuritis and to examine cerebrospinal fluid dynamics in the subarachnoid space, employing the method of standardised echography and the '30 degrees test'.

Optical-acoustic effect in laser optics investigations [PDF]
Parameters of the acoustic signals (AS) excited in the massive Al, Be and Cu mirrors by TEA CO2- and Nd : glass-laser pulses were investigated. Correlations between the AS parameters and an emergence of different types of laser-induced damage such as evaporation of heat insulated defects, melting and optical breakdown off irradiated surface have been ...

Investigation towards Laser Cleaning of Corrosion Products from Lead Objects
In this work lasers with micro-, nano-, pico- and femtosecond pulse durations were used to clean atmospheric corrosion products from the fragments of a 19th-century lead outdoor sculpture. The state of the surface was studied by optical microscopy, Raman
