Summary

Story summary

Researchers at Chiba University in Japan developed a compact method to generate nondiffracting optical bottle beams that maintain shape and intensity over long distances.
They convert a Gaussian beam to a modified Bessel beam with a binary axicon and focus it with a multilevel diffractive lens (MDL).
Funding from notable science agencies highlights the work's international significance and its potential to advance imaging, particle manipulation, micromachining, and quantum optics.
