What is the principle of laser?
Many people wonder: What is the principle of laser? It's simpler than you think. Laser light is totally different from light from incandescent bulbs or LEDs. The key is that laser is a coherent light source. It has an optical oscillator that boosts light intensity while keeping the light field phase stable.
The laser principle relies on stimulated emission amplification-this is where the acronym LASER comes from. When an atom is excited, it emits a photon identical to an existing one. This "cloned" photon has the same phase, frequency, direction and polarization as the original. That's coherence. It's what makes laser have unique optical properties.
A laser has three core parts: gain medium, pump source and resonant cavity. The pump source creates population inversion in the gain medium-this is a must for stimulated emission. The gain medium ensures effective laser emission and desired output performance. The resonant cavity's mirrors reflect incoherent photons from spontaneous emission back into the gain medium. Stimulated emission copies these reflected photons. Continuous reflection and amplification produce a lot of coherent photons. Some of these photons pass through a partially reflective mirror to form the laser beam we use.
These unique laser properties make it perfect for 3D/4D Laser Level Professional and Craftsman Self Leveling Laser Kit With Tripod. Laser beams don't diverge much, even over long distances. They can also focus into a tiny spot. This means high precision-exactly what you need for construction, renovation or DIY projects.
