It is often defined at the 1/e 2 width, which is bounded by the points where the beam’s intensity reaches 1/e 2 (≈ 13.5%) of its maximum value.

WebThis differentiates the fiber laser to other types of laser available on the market, where the active laser medium is a crystal (e.g. disk laser) or gas (e.g. CO 2 laser). Fiber lasers provide absolute efficiency, precisely control speed and power through accurate management of the beam length, duration, intensity, and heat output. WebLaser light has extra-ordinary properties which are not present in the ordinary light sources like sun and incandescent lamp. The conventional light sources such as electric bulb or tube light does not emit highly directional and coherent light whereas lasers produce highly directional, monochromatic, coherent and polarized light beam.
