Abstract
A method and apparatus for optimising the output of a multi-element laser, typically a multi-rod laser is disclosed, the method comprising obtaining a graph of power output against power input for the resonator, selecting an instability point where the output dips, measuring the power output at that point, selectively altering the gains of each of the power supply means supplying each of the laser elements, and selecting an optimum combination of gain values to provide maximum output power at that point.
