WebLED emits light as the consequence of charge carriers recombination across P-N Junction, while LASER emits light as a result of photons striking the atom and compels them to release the similar photon. A laser works on the principle of stimulated emission and LED works on the principle of Electro-luminance. WebSep 2, 2024 · LED is usually a polychromatic, i.e. it produces a broader band of wavelengths. LASER is a monochromatic source of light as it generates the light of single wavelength. Coherence. LED is a non-coherent source of light, i.e. its photons are out of phase, LASER is a coherent source of light, which means its photons are in phase.
