The beams are then overlapped on amaterial surface to form an interference pattern. If the power of the laser beam is sufficiently high, material removal can occur at the interference maxima through processes such as remelting, evaporation and ablation, while the material at the interference minima remains mostly intact. In this way, a large ...
This effect is called beam squint. Both the Blass matrix and Butler matrix suffer from beam squint and the effect limits the bandwidth that can be achieved. [29] Another undesirable effect is that the further a beam is off boresight (broadside beam) the lower is the beam peak field. [30] The total number of circuit blocks required is
Upon post-exposure photolithographic processing, a photoresist pattern corresponding to the periodic intensity pattern emerges. For 2-beam interference, the fringe-to-fringe spacing or period is given by / (), where λ is the wavelength and θ is the angle between the two interfering waves. The minimum period achievable is then half the ...
Such materials have the potential to simplify the design of high brightness green lasers. Neodymium glass (Nd:Glass) laser ~1.062 μm (silicate glasses), ~1.054 μm (phosphate glasses) Flashlamp, laser diode Used in extremely high-power (terawatt scale), high-energy multiple beam systems for inertial confinement fusion.

A diffractive beam splitter can generate either a 1-dimensional beam array (1xN) or a 2-dimensional beam matrix (MxN), depending on the diffractive pattern on the element. The diffractive beam splitter is used with monochromatic light such as a laser beam, and is designed for a specific wavelength and angle of separation between output beams.
