Abstract:
1. A monoblock laser apparatus, comprising: a substrate aligned along an axis and having a first recess therein, the substrate having a first support immovable with respect to the substrate, adapted to fit into the first recess, and having two inner sides to provide mechanical support; an HR mirror immovably affixed to the substrate, for reflecting light; an OC mirror immovably affixed to the substrate and disposed along the axis, for reflecting light and passing a remainder of the light therethrough; a gain element adapted to amplify and polarize the light, the gain element immovably affixed to the substrate and disposed between the OC mirror and the HR mirror; and a first Risley wedge pair adapted to rotate about the axis until an optimal rotation position is reached, the first Risley wedge pair having a substantially circular cross section and substantially supported between the two inner sides of the first support, the first support positioned between the HR mirror and the OC mirror, wherein light reflected from the HR mirror passes through the first Risley wedge pair and the gain element and partially through the OC mirror to provide a laser output, wherein the first Risley wedge pair is fixed in the rotation position based on a desired threshold in the laser output.
