Holographic beam combiner

1999 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference, 2003
There are numerous applications for a device that can combine multiple laser beams into a single one. For example, a compact, high power ladar (laser radar) can be realized by combining the output of many diode lasers. Here, we demonstrate the basic features of a holographic device which has the potential to combine upto 20 laser beams into one high ...

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.

Grating Beam Combiner.

1982
Abstract : The fabrication, test, and analysis of a two-wave length dual-frequency beam sampling grating has been performed. Measurements of the efficiency, diffracted wavefront quality, frequency ratio, and skew are described. Analysis of the effects of nonzero skew and frequency ratio residual on its performance are presented, as well as the required

Fully symmetric nulling beam combiners

Applied Optics, 2001
A simple method of nulling broadband light is presented. A mirror-symmetric pair of right-angle periscopes is first used to introduce a geometric field flip between two incident light beams, after which the light is combined by means of one of a number of constructive two-beam interferometers.

Subwavelength diffractive color beam combiner

Applied Optics, 2014
A high-efficiency subwavelength diffractive beam combiner operating in a visible spectral range is designed, fabricated, and demonstrated. Such a device combines red, green, and blue color beams into one output light beam. Diffraction efficiencies of different types of gratings are calculated for various materials, incidence angles, and polarizations ...

Azimuthal multiple-beam interference effects with combinations of vortex beams

Optics Letters, 2015
We create a series of vortex beams consisting of positive and negative topological charges and develop a geometry where they interfere creating azimuthal multiple-beam interference effects. Usually the combination of two beams with opposite charges creates an azimuthal two-beam interference effect where the intensity varies sinusoidally with azimuthal ...

Theoretical research of beam combination between hollow beam and Gaussian beam

SPIE Proceedings, 2017
The near and far field intensity distribution as well as the beam quality of the combination between the hollow beam generated by double axicons and the Gaussian beam were simulated in this paper. The simulation results revealed that several parameters like the interval between two axicons and the phase difference between the two beams would influence ...

Combining beams from separated telescopes

Applied Optics, 1986
In the present paper, work is discussed which arose in the context of optical design studies for the proposed space-based COSMIC (Coherent Optical System of Modular Interferometric Collectors) telescope. The operation of COSMIC involves the combination of a number of parallel beams with a central beam-combining telescope which forms an image of the sky.
