Abstract
Abstract An inventive system integrating a laser head and power supply in a novel fashion is described. The integral laser head and power supply utilizes a power supply heat sink which circumferentially surrounds the laser head. Also incorporated is a circuit board so sized and configured to allow for placement of the laser head therein. High technology components are also preferably employed to allow minimization of size and weight. The resulting integral laser head and power supply enjoys a significant reduction, approximately half, in both size and weight.
