Abstract
An optical processing head capable of reducing the energy loss at the time of optical processing is disclosed. The optical processing head includes a first optical element that converts light emitted by a light source into first parallel light, a second optical element that is arranged downstream of the first optical element and converts the first parallel light into first divergent light, a third optical element that is arranged downstream of the second optical element and converts the first divergent light into second parallel light, and a fourth optical element that is arranged downstream of the third optical element and converts the second parallel light into convergent light which is condensed on the processing surface side.
