Self-bending of a cw laser beam in sodium vapor.

چکیده
Continuous-wave self-deflection of an asymmetrical laser beam, with a deflection angle up to eight diffraction widths, and strong attenuation of the on-axis radiation were achieved in a short sodium-vapor cell. We determined that the nonlinear refractive index Deltan varied almost linearly with intensity I, Deltan approximately n(2)I, with n(2) ~ -10(-7) cm(2)/W at ~200 degrees C and intensities less than 220 W/cm(2).

Continuous-wave self-deflection effect in sodium vapor
Observations of the self-deflection effect for an asymmetrical continuous-wave laser beam in sodium vapor are described, and comparisons based on theoretical calculations are made. A self-bending angle as large as eight diffraction widths was recorded, and strong attenuation of the on-axis radiation due to self-bending was measured. At -200'C the self-deflection angle increased linearly with be...
متن کاملSelf-bending of light: comment.
This Comment addresses an observed effect that we believe has been inaccurately identified by Xing et al.1 The reported effect is not self-bending, as they suggested, but rather a cross-phase modulation effect. The self-bending effect2 has, for 24 years, been defined as a degenerate process whereby a beam of wavelength A induces an intensity-dependent index change that deflects the trajectory o...
متن کاملStabilization of transverse solitary waves by a nonlocal response of the nonlinear medium.
Optical pumping of atomic vapors can lead to self-focusing of resonant laser beams. The saturation of the optical pumping process at low intensity allows the study of transverse solitons in the form of selftrapped laser beams, using low-power cw lasers. The long lifetime of the optically pumped atoms allows the atomic diffusion to transport the excitation away from the interaction region. Numer...
متن کاملLaser frequency translation: a new method.
We demonstrate how the frequency of a single-mode cw dye laser can be translated by 1.772 GHz using stimulated Raman scattering in sodium vapor. The output of a sodium Raman laser, the frequency-translated beam, is shown to be highly correlated in frequency with the dye-laser pump beam. The bandwidth of the 1.772-GHz heterodyne beat signal between the two beams is found to be as narrow as 440 H...
متن کاملPrediction of Bending Angle for Laser Forming of Tailor Machined Blanks by Neural Network
Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...
