The wave equation can be solved without diffraction in the Cartesian coordinate system, cylindrical coordinate system, elliptic cylindrical coordinate system and parabolic coordinate system, which are Cosine beam, Bessel beam, Mathieu Beams and parabolic beams, Airy beams...they form the family of non-diffracting beams (also known as Helmholtz beams).

In recent years, with the rapid development of laser technology, a variety of non-diffraction beams with the same center spot after long-distance transmission have been produced successively. It has a wide range of applications in the fields of manipulation, optical communication, plasma guidance, photobomb generation, optical communication, synthesis of self-focusing beams, and nonlinear optics.

UPOLabs standardizes the phase field generated by the non-diffracted beam through software, and can quickly obtain different types of non-diffracted beam by using the software. Combined with the spatial light modulator system, a fast experimental platform is built. UPOLabs non-diffraction beam experimental system can help researchers engaged in non-diffraction beam research to quickly become familiar with various beam generation modes with known characteristics, and then optimize and explore more beam characteristics.
