Intra-cavity optical modulators: Optical shutters

Optical-mechanical shutter with the prism of total internal reflection. In this shutter a prism BР-1800 is used, which is revolved on the axis of high speed electric motor. The ribs of prism are perpendicular to the axis of rotation     more...

Extra-cavity optical devices of control of laser beam in time: Acousto-optic modulators

Principle of work of acousto-optic (AO) modulator is based on excitation in the AO environment of running bulk acoustic wave (RBAW) and creation of phase diffraction grating, on which the diffraction of optical radiation appears.     more...

Hot quanta from the cold water: liquid dye lasers

The active environment of dye laser includes the organic matter dissolved in a liquid solvent. The optical pumping of solution is executed with the help of other laser or pulsed lamp. Hereupon population inversion of active environment appears this creates at certain terms the emission of laser radiations.     more...

Perspectives of application of gas laser technologies in the solar power systems of production and transportation of energy

The gas laser was the first continuous-light laser. Gas lasers using many gases have been built and used for many purposes. The purpose of the article is the analysis of the possibility of application of gas laser technologies in the solar power systems of production and transportation of energy.     more...

Stimulated emission in semiconductor laser structures – a step to the new high effective coherent PV solar cells

Today’s semiconductor lasers radiate in a red and near infrared (IR) ranges of light-spectrum and have high energy effectiveness about 50%. The high levels of output power are attained, which allow replacing traditional lasers in a row of applications.     more...

"New study shows breakdown in Planck's law"

Scientists had never been able to confirm, or measure in practice, the breakdown in well-established physical law that describes the transfer of heat between two objects, when the objects are very close together
