Abstract

In this paper, we have introduced a measurement scheme for the wedge angle and bending of the faces of the laser disk active medium. To increase the efficiency of the laser, the front face of the medium has been coated with an antireflection coating. In addition, a small wedge angle between the two faces of the medium has been considered to avoid the etalon effect inside the medium. Pumping the active medium causes thermodynamic effects and deformation of the faces of the medium. Characterization of this deformation is necessary for designing an adaptive optics and retrieving it in the resonator. For this purpose, a visible laser has been utilized which unlike the pumping beam has multi reflections from the faces of medium and contains the information of both wedge and bending. We have demonstrated that with a single shot interference pattern the information of the wedge and front and back faces of the medium can be measured.
