I need a laser that is easily transported from one operatory to another; do you have any suggestions for a light, portable soft tissue laser?

The lightest, most portable laser on the market now is called NV Microlaser (Discus Dental). It is literally the shape of a pen and weighs only 1.9 ounces. It is activated with a wireless foot pedal and can easily be carried from one operatory to the next.
