Laser tracking responds to the slightest hand movement with extraordinary accuracy. It does do on virtually any surface- white or black- solid or pattern- shiny or matte. Laser illumination tracks flawlessly on the high-gloss surfaces that LED-based mice simply can't negotiate. There surfaces include lacquered tabletops- glazed ceramic tile- un-textured plastic- metal surfaces- photo paper- laminate countertops- opaque glass- and more (Laser still may not track on mirrored or clear surfaces- such as windowpane glass).

The optical sensor reads the image at a rate of about 1-500 times per second. The problem with this is sometimes differences in similar patterns are not easily distinguishable because of the lower resolution and power of the LED. Therefore it compromises the tracking accuracy depending on the surface (i.e.. certain mouse pads with certain patterns/surface textures). Laser is based on the same idea except it uses a narrow beam of light that is reflected off the surface producing an image with greater contrast that is captured by a higher resolution sensor (1600dpi) at a higher rate- of up to 6000-7000 times per second. Because of this advancement- laser can track where optical can't.
