Standards for laser safety: origins, level, perspectives Introduction in 2009 in the territory of the CIS of a copy of European standard IEC 60825-1-2007 Safety of laser products in parallel with the existing Sanitary Standards has laid the foundation to confusion in the normative legislation. The legalized standards contain the whole complex of mutually excluding requirements.

Localization of pulsed radiation in photonic crystal A single Gaussian pulse propagation through a two-dimensional photonic crystal is considered. The spectrum of photonic crystal corresponds to the both permitted and forbidden frequency ranges for the passage of radiation. The possibility of radiation localization within the photonic crystal with finite dimensions is shown.

Metamaterials: myth or reality? "Reverse" refractive index. Part 1 The concept of the materials with reverse refractive index, i.e. metamaterials, in optical spectral region, the possibility of implementation of “superlens”, “cloak of invisibility” etc. The attempt to prove reasonably that a part of the scientists who are engaged in this subject mistake the wish for the reality and take advantage of theoretical calculations.

Lidar sounding of iodine molecules in atmosphere Content of heavy iodine isotope in the air close to the nuclear power plants or other radiochemical enterprises can be an indicator of the radioactive contamination. Laser measurement methods of molecular iodine concentration in gaseous media rely to the results of numerical simulation methods.

Dual-channel optical pulse oximeter on the base of laser sensors to solve actual problems in medical practice Pulse oximetry is a noninvasive method of measurement that provides information about the patient’s oxygen saturation of the blood. It is widely used in different areas of medicine. However, there are basic unresolved problems associated with the production of new urgent medical requirements for quality of biosignals registration, monitoring, measurement and processing.
