More particularly, the first set of flexures can include first and second flexures that are opposite one another and configured such that movement of the support element in the first dimension is allowed, but movement of the support element in the second and third dimensions is prevented. The second set of flexures can include third and fourth flexures that are opposite to one another and configured such that movement of the support element in the second dimension is allowed, but movement in the first and third dimensions is prevented. The micropositioner may be included in a system for pointing a laser beam.
