Coherent beam combining of cylindrical vector beams for power scaling

Optics Letters, 2023
Coherent beam combining (CBC) of cylindrical vector beams (CVBs) based on an active phase controller is proposed and demonstrated. Experimentally, two pieces of spatially variant wave plates (S-wave plate) were employed as vector mode convertors for two individual 1064-nm fiber amplifier channels. When the system was in a closed loop, a combined output

Laser beam power control device

Journal of Physics E: Scientific Instruments, 1968
A simple, reliable device for continuously varying the intensity and plane of polarization of laser beams over a wide range is described. It consists of a series of transparent dielectric plates set at the Brewster angle and capable of rotation about the incident beam axis.

Laser–particle interactions in shaped beams: Beam power normalization

Journal of Quantitative Spectroscopy and Radiative Transfer, 2013
Abstract We present a semi-analytic theory for calculating light–particle interactions in shaped laser beams even when the paraxial beam description is invalid. It requires weighting the expressions for the cross sections with a beam normalization parameter, ϰ , associated with the incident power.

High-power CO2 laser-beam monitor

Review of Scientific Instruments, 1978
A diagnostic system for measuring the beam power and quality of a high-power cw CO2 electro-aerodynamic laser is described. A ZnSe beamsplitter was employed to split off a small fraction (0.5%) of the main laser beam for diagnostic purposes. The low-power beam was split again to provide two beams for power and energy-distribution measurements ...
