ABSTRACT:
A cutting tool such as a laser knife comprises a passage for a beam of light, a layer of single crystal diamond located in the passage to intercept the light passing down the passage, the diamond layer presenting a surface for the incoming light and a surface for the outgoing light, and an anti-reflective coating bonded to at least one of the surfaces. The anti-reflective coating is typically a silicon ceramic material for wavelengths not exceeding 2 .mu.m and typically a polycrystalline diamond for wavelengths of at least 2 .mu.m.
