Abstract
Growing applications of CO2-lasers in many cases demand transmission optical elements (widows, lenses, etc.) which could reliably operate at high beam powers. In the present work we propose to produce CVD diamond transmissive diffractive optics. To realize this idea surface microstructuring by laser ablation was applied. Computer controlled selected area ablation of preliminary polished (plane) diamond plates with thickness of 0.3 mm was performed by scanning focused beam of KrF laser. As a test sample for radiation with (lambda) equals 10.6 micrometers a cylindrical lens with the aperture of 4 X 4 mm2 and focal length of 25 mm was produced. Numerical simulation of the lens was made for the fundamental mode TEM00. For tests of the diamond lens 20 W CO2 laser was used.
