Abstract: Coherent beam combining of 2-μm fibre lasers is studied numerically. Such lasers are a suitable candidate for creation of a beam combining module due to their higher nonlinear effect and optical damage threshold compared to their 1-μm counterparts. The calculations results show that radiation of a 1-μm fibre laser has a better focusing property in free-space due to a smaller wavelength, whereas a 2-μm laser beam has a better focusing capability in the target-plane under conditions of real atmospheric turbulence.

Keywords: fibre laser, coherent combining of laser beams, laser beam focusing.
