Analytical Study on the Steady-State Thermal Blooming of Incoherent Combining Beam
Atmosphere, 2022 The incoherent combined beam of lasers has many important applications due to its simple technology and excellent expansibility. Thermal blooming is one factor that will seriously affect the propagation of the combined beam in the atmosphere.

Scaling potential of beam-splitter-based coherent beam combination
Optics Express, 2021 The impact of nonlinear refraction and residual absorption on the achievable peak- and average power in beam-splitter-based coherent beam combination is analyzed theoretically. While the peak power remains limited only by the aperture size, a fundamental average power limit is given by the thermo-optical and thermo-mechanical properties of the beam ...

A method to achieve spectral beam combining based on a novel symmetric grating
Frontiers in Physics, 2022 A symmetric grating is proposed to obtain higher output power in spectral beam combination by increasing the number of lasers and spectral utilization. The grating allows laser beams to be incident from both sides of the grating normal to achieve coaxial

Segmented vortex wavefront coherent beam combining
AIP Advances, 2022 A concept of a coherent beam combining with a segmented vortex wavefront (V-CBC) was proposed to generate a dark optical trap. Three-dimensional (3D) irradiance distributions in the caustics of V-CBC were modeled.

Interferometric beam combination with discrete optics [PDF]
Optics Letters, 2010 We explore the capabilities of discrete diffraction in phase retrieval problems and propose an innovative scheme exploiting a two-dimensional array of coupled waveguides to determine the phase and amplitude of the mutual correlation function between any pair of three telescopes of an astrointerferometer.
