A quirk in scientific 3D modeling has led to the discovery that laser light can — under the right circumstances — cast its own shadow. The finding challenges our current understanding of what ...

A multi-photon (7 × 7)-focus 3D laser printer based on a 3D-printed diffractive optical element and a 3D-printed multi-lens array, Light: Advanced Manufacturing (2024). DOI: 10.37188/lam.

No, for two reasons: 1.) The laser is moving and it never has constant focus at any one location (think PWM, you’re not shining at full power on any one location). 2.) The power of this unit is ...

“The technology uses less expensive light sources as simple as a laser pointer ... and health care. Femtosecond laser two-photon polymerization is widely used for 3D nanostructure fabrication.
