• Figure 7. Bending of green laser light towards the left (dimensions of the photo: 500× 700 mm). 3. Conclusion
• In this experimental study, semiconductor laser diodes and LEDs were used as light sources. Specifications for
• the lens used are provided above. Apart from these components, there were no other parts made of special
• materials. While it is commonly assumed that a laser beam expands along its path, it is clearly shown in Figure
• 7 that, contrary to common assumptions, the beam contracts. Due to some technical reasons, we are unable
• provide other details of the experiment. Here we share the results with our colleagues. In the experiment, only
• the observed cases are discussed. The authors would like to discuss the findings of the experiment with other
• scientists interested in this issue and look forward to their support, suggestions, and criticism. 4. Acknowledgments
