ABSTRACT:
A device for generating a high power frequency converted laser beam includes a nonlinear optical crystal having an entrance surface and a curved surface. The nonlinear optical crystal is configured to receive at least one laser beam at the entrance surface and provide a frequency converted beam through a frequency conversion process. The device also includes an optical coating coupled to the curved surface. The reflectance of the optical coating is greater than 50% at a wavelength of the frequency converted beam. Additionally, the far field divergence angle of the frequency converted beam increases after reflection off the curved surface. The device further includes a heat sink in thermal contact with the optical coating.
