Holography is used in the laser field primarily for recording and reconstructing three-dimensional images using coherent light. Lasers provide the necessary coherence and monochromaticity, allowing for the precise interference patterns required to create high-quality holograms. These holograms can be used in various applications, including data storage, imaging, and security features on credit cards and identification documents. Additionally, holographic techniques are employed in laser diagnostics and metrology to analyze light fields and measure distances with high accuracy.

What are the uses of helium neon laser?

HeNe laser is used to determine the concentration of a fluid , its application is widely used in the engineering field, esp by chemical engineers. In a CSTR reaction, I myself used the HeNe laser to determine the concentration of the effluent reactants with the help of a detector. with the use of absorbency equations and little bit of math u can determine the concentration of your sample/reactants...etc.
