A laser resonator has a support disposed on its axis, to support an adjustable element rotatable with respect to the axis. An HR mirror reflects light, which passes through gain element means and partially through an OC mirror to provide a laser output. The adjustable element is fixed in rotation upon reaching a pre-selected laser output. One embodiment features a support comprising a recess in the substrate of the resonator, and one of the mirrors is formed on the spherically shaped bottom of the adjustable element. Alternatively, the adjustable element comprises a first Risley wedge pair rotatable within a V-block shaped support. Alternatively, a recess in the substrate supports the HR mirror and a Risley wedge pair.Both embodiments and their variations apply to two stage resonators, which then include a second support, appropriately placed wavelength shifting means and other optional optical elements.
