Diffractive Optical Elements (DOEs)



Diffractive Optical Elements (DOEs)

Diffractive optical elements (DOEs) or digital diffractive optics are special types of optical phase components that use micro-structures to modify an input laser beam’s phase. Therefore, diffractive optical elements can manipulate the input beams in a variety of ways, creating different light patterns and shapes that are quite difficult to accomplish using refractive optics. Even though some methods involving refractive optics can achieve a similar type of beam manipulation, those require expensive, bulky, and very complicated optical components. As DOEs follow the principle of diffraction and involve micro-structure, they are suitable for use in infrared systems, Uv laser systems  and many  other laser systems.

If you are wondering why we need to modify the phase of the laser beams, then the answer is we require a unique and precise beam distribution pattern other than the Gaussian distribution pattern that we get from most laser beams. You can observe a significant energy loss in the Gaussian distribution pattern and that is not acceptable for various laser beam applications, including medical treatments, imaging, printing, sensing, and materials processing.

The Advantages of Diffractive Optical Elements

There are several advantages of using diffractive optical elements in beam splitting and shaping, such as

  • The angular accuracy will be perfect with no tolerances.
  • As DOEs are lightweight, flat, and thin, they can easily be integrated in optical beam paths and enable beam splitting and shaping with a single solid component.
  • DOEs require low maintenance and are robust.

.Types of Diffractive Optical Elements

Diffractive optical elements can modify a laser input beam in different ways and generate different functions. There are  three main types of DOEs:

  • Diffractive Beam Splitters:

Diffractive beam splitters are different from conventional optical beam splitters in terms of accuracy in splitting an incoming beam into any expected number of identical output beams. Every output beam possesses the same characteristics as others and a controlled angular separation. Beam-splitting DOEs also help obtain different shapes for the distribution pattern of the output beam, such as round, square, line, hexagon, etc. These DOEs are customizable for obtaining any desired angular separation, intensity, wavelength between UV and IR, and order numbers.

  • Diffractive Beam Shapers:

Diffractive beam shapers help obtain a consistent intensity distribution pattern (flat-top distribution pattern) by manipulating an input beam. Analytical top-hat diffractive beam shaper and diffractive diffuser are two types of diffractive beam shapers. Both beam shapers are useful to obtain any desired shape of the intensity profile, including rectangle and round.

  • Beam Foci Elements:

Beam foci elements are useful to modify the input beam’s focal properties. Beam foci elements can alter the depth of focus, generate multiple foci with controlled angular separation between them, and bring beams with multiple wavelengths into focus on a single focus plane.
