5 watt Endurance laser pointer.

Exploring 445 nm multimode NUBM44/47 (LD) NICHIA laser beam.

Some interesting effects.

Longitudinal laser beam interference

Observe a central mode

The laser beam can disappear completely, and then reappear after a few meters

The interference pattern in the air is very unstable and constantly «breathing», but it is still clearly visible.


Interestingly, when the laser beam passes through the smoke of a fire, it is clearly seen that the laser beam interacts with the smoke only in a certain place, and then continues on its way, and the brightness does not visually change much.
