Is laser mouse optical mouse?

There are quite some differences between an optical mouse and a laser mouse.

One of the most noticeable differences is the type of rays coming out of the mouse. Now,we all know that from an optical mouse there is (usually) a red light coming out and on the other hand, the laser mouse does not produce such light. It produces an invisible laser beam which is harmless to humans.

Also,they say,that laser mouses are much more precise than the previous generation mouses, 'thus making them much more valuable.

And finally, you can use laser mouses on almost all surfaces (except glass, mirrors and air) which is quite useful in many situations.

Of course,there are many people questioning which is better - the laser mouse or the optical mouse,but one thing is for certain - they may look the same,but they are definitely not the same thing.
