The size of the spot scales with wavelength, so a laser at 355 nm can be focused to a much smaller spot (e.g., less than 10 µm). For an infrared laser with a wavelength of 1064 nm, a typical spot size can't be… Related Searches: cylindrical lens

Two copies of the original wavefront are laterally shifted by the diffraction angle defined by the grating period. Both diffracted wavefronts see the same shift but in opposite directions. The optical path length is therefore the same for both beams… Related Searches: coherence length | spatial filter | laser pdf | top hat profile
