Synthesis of DOE on polycrystalline diamond films

11.1 Formation technology of the microrelief on the surface of diamond films

Despite the widespread use of IR lasers for solving technological problems [13] (laser cutting, bending, welding, spraying, etc.), the establishment of a transmission functional optics (including diffractive), able to work with high power infrared radiation (over 10–20 kW) until recently remained open, mainly due to the lack of optical materials with appropriate thermal properties and technologies of their processing.

The specificity of the problems of laser technology brings special demands on diffractive optical elements for applications:

• the implemented diffractive microrelief should ensure that a given distribution ...
