laser beam
Thin films of the hyperbranched azo polymers were used to fabricate surface-relief-gratings (SRGs) by exposing them to an interference pattern of Ar+ laser beam at modest intensities (150 mW/cm2).
      
Other than these, surface modification as well as laser beam welding are also involved.
      
A thermocapillary depression is induced by a laser beam in a layer of a transparent liquid on an absorbing substrate.
      
The diameters of the thermocapillary response formed by the laser beam on a screen are studied in their dependence on the curvature of the equilibrium liquid meniscus formed between the plates.
      
This increases the divergence of the laser beam and reduces the population inversion of the vibrational levels of the CO2 molecule [1] because of the growth of the temperature and the density behind shock waves.
      
The heat source could be a laser beam or a hot body.
      
The two-dimensional problem of the convective motion of the gas in an optical discharge burning in a vertical CO2 laser beam inside a cylindrical chamber is solved.
      
Strong Self-Induced Distortion of a Laser Beam in a Longitudinal Gas Flow
      
A method for the approximate description of the propagation of an intense optical beam using mean transverse dimensions and displacements of the center of gravity is extended to longitudinal gas flows past a laser beam.
      
It is shown that the experiments with annular distributions can provide additional confirmation of the hydrodynamic mechanism of liquid bleaching by a laser beam.
      
It was demonstrated that high-quality continuous patterns can be fabricated using one scan of the laser beam.
      
In the PVK-matrix composite containing 0.26 wt % SWNT and 3 wt % C60, the beam-coupling gain coefficient Γ of a 1550-nm laser beam and the net gain Γ-α are 32 and ~27 cm-1, respectively, at a constant field of E0 = 140 V/μm.
      
The solution of the heat equation for a cylinder with due regard for the Gaussian distribution of energy over the laser beam cross section forms the basis of the measurement method.
      
The threshold characteristics of the laser beam parameters are determined, which are sufficient for the initiation of optical breakdown on droplets of dielectric liquid.
      
A Position-Sensitive Photodetector for Studying the Spatial-Time Radiation Intensity Distribution in a Laser Beam
      
A position-sensitive nine-sectional photodetector for studying the spatial-time distribution of the radiation intensity in a laser beam is described.
      
An Installation for Obtaining Intense Flows of Multiply Charged Laser-Plasma Ions Using a Second Laser Beam
      
The design of a compact single-mirror electromechanical system for the two-dimensional scanning of a laser beam is described.
      
A polarointerferometer designed for studying magnetic fields in high-temperature laser or electricdischarge plasma with the method of measuring the Faraday rotation of the plane of polarization of a probing laser beam is described.
      
In the solid phase, organic molecules were ionized by an ultraviolet laser beam generated in accordance with the matrix-assistant laser desorption and ionization (MALDI) procedure.
