Laser is concentrated light. While plasma is super heated material. The material, or substance if you will, can be anything from gas to stone or whatever. A real life plasma cutter is not the same as a real life laser cutter. What would be an (obvious) indicator to that laser and plasma is not the same is that is that lasers are often used in harmless devices used in our daily lives such as a CD/DVD/BD player  or a laser pointer.
