Patent ID: 7050475

Claim:
A laser comprising: first and second electrodes provided at different elevations and which are approximately parallel to one another, first and second sectional sidewalls provided at least partially between the first and second electrodes, an elongated cavity defined between opposing major surfaces of the first and second electrodes and between the first and second sidewalls, and wherein an optical axis of the laser is defined at least partially in the elongated cavity along a lengthwise direction of the cavity so that the optical axis is provided between opposing approximately parallel surfaces of the first and second electrodes, at least one protrusion on the first and/or second electrode, the protrusion extending into the cavity from the first and/or second electrode so that the protrusion extends from a main body of the first and/or second electrode into the cavity in a direction transverse to the optical axis of the laser; and wherein each of the first and second sectional sidewalls comprise adjacent sections that are spaced apart from one another.
