A laser might look like just a bright beam of light — but it’s one of the most precise tools humans have ever created. 🔥💫

Unlike ordinary light, which scatters in all directions, laser light is perfectly aligned — all photons move together in the same direction and frequency.
It all starts when atoms are excited by energy. They release photons that trigger other atoms to emit identical photons, creating a synchronized chain reaction called stimulated emission — the “SE” in “LASER.”

That’s why lasers can cut metal, scan barcodes, and even perform eye surgery with incredible accuracy.
From science labs to your pocket laser pointer — it’s all about light, perfectly under control. ⚡
