Direct Laser Interference Patterning (DLIP) - a new method.[1] of creating repetitive patterns on the surface of materials by using the interference phenomenon of two or more laser beams.[2] In order to obtain interference, the beam should be split in one of the interference systems. In such an arrangement, the beam is divided, for example, by a beam splitter, special prisms[3] or other element. Then the beams are folded together and form an interference pattern. Sufficiently high power of the laser beam can thus result in the removal of material at the interference maximums thanks to ablation phenomenon, leaving the material intact at the minimums. This way, a repeatable pattern is obtained permanently fixed on the surface of a given material.[citation needed]
Advantages of the method
- It is possible to create microstructures directly on the material on a scale much larger than in the case of direct laser writing (DLW). The image created as a result of interference has dimensions of even the order of single centimeters, which enables the creation of a large surface structure in a single technological step.
- Another important advantage is that the number of elements in the experimental setup is reduced due to the interference phenomenon.
- The dimensions of the microstructure are in the order of 100 nm, which is not achievable with direct laser writing.
Types of interferometers
There are many ways to separate the laser beam. Selected types of interferometers based on such elements as:
- prisms[3]
- laser beam dividers[2]
- diffraction gratings[4]
- DOEs (diffractive optical elements)[5]
- Lloyd (based on perpendicularly placed and connected mirrors)[6]
