Abstract:
1. A pumping module for pumping at least two laser crystal rods, each of the laser crystal rods having an optical axis, comprising: a first set of laser diode arrays disposed around a first laser crystal rod, the laser diode arrays being approximately equally spaced around the first laser crystal rod, each of the laser diode arrays of the first set including laser diodes that arc disposed in a plane that is substantially orthogonal to a first longitudinal axis of the laser crystal rod, the laser diodes of the first set emitting light that substantially uniformly pumps the first laser crystal rod; and a second set of laser diode arrays disposed around a second laser crystal rod, the laser diode arrays of the second set being approximately equally spaced around the second laser crystal rod, each of the laser diode arrays of the second set including laser diodes that are disposed in a plane that is substantially orthogonal to a second longitudinal axis of the second laser crystal rod, the laser diodes of the second set emitting light that substantially uniformly pumps the second laser crystal rod, wherein the first longitudinal axis and the second longitudinal axis are optically aligned along an optical axis, and wherein the second set of laser diode arrays is disposed at an angle of rotation around the optical axis with respect to the disposition of the first set of laser diode arrays around the optical axis.
