Concave mirror laser beam waveguide for a carbon dioxide laser surgery system.
An improved articulated laser beam waveguide with seven mirrors was developed for a carbon dioxide laser surgery system. Four concave mirrors were introduced to suppress the accumulating off-axis error and to control the beam diameter of the propagating laser beam. Each curvature of the concave mirror was determined to be optimum according to the calculation of off-axis errors and Gaussian beam parameters of the propagating laser beam. An experiment demonstrated the merits of introducing the concave mirrors according to the proposed design procedure.
