Difference between Optical Mouse and Laser Mouse. Key Difference: The optical mouse uses a light-emitting diode, while a laser mouse uses a laser in order to detect movement. A mouse is hardware that is required when trying to navigate on a desktop PC. However, many people these days also use a mouse on their laptops as it makes navigation easier.
A laser is different in three main ways: 1- The light emitted from a laser is monochromatic, that is, it only has one wavelength (color). Ordinary light on the other hand, i â¦ s a combination of many different wavelengths (colors).2- It is coherent, that is, the waves of light of the laser are in phase.nswered by The Community.
