What are the effects of atmospheric turbulence on the coherence of a laser beam? How can adaptive optics be used to mitigate the effects of turbulence on coherent light in free space?

Dec 3, 2022 ... Two coherent sources of light have the same frequency and are located at positions P1 and P2. Suppose at t=0, waves of equal amplitude A are emitted but 180 ... The source which emits a light wave with the same frequency, wavelength and phase or having a constant phase difference is known as a coherent source. A ... cient, tuneable, compact light sources for the mid infrared (2700 nm < λs,i <. 3500 nm) spectral range. Keywords: nonlinear optics; parametric frequency ...
