Uncovering the remarkable contribution of lasers peak intensity region in holography

For the scheme of two colour lasers in interference and holography, we uncover remarkable contribution focusing region (spread) peak intensity superposing laser beams based on numerical studies confirm it by mathematical calculations. The pulses having for a wider create better pattern, leading to higher modulation depth. Also, such stronger gradient enhance range frequency detuning (difference), which would improve experimentation towards generating holograms. A comparison results achieved with is done most commonly used Gaussian beams, understanding concept advancements holography.
