LASER HEAD FOR IRRADIATION AND REMOVAL OF MATERIAL FROM A SURFACE OF A STRUCTURE

摘要

A laser head (1200) is adapted to irradiate an interaction region of an inhabitable structure with laser light to remove material from the structure. The laser head (1200) includes a housing (1230) and a connector (1210) coupled to the housing (1230) and optically coupled to a laser generator. The connector (1210) is adapted to transmit laser light from the laser generator. The laser head (1200) further includes a first optical element (1235) and a second optical element (1235') contained in the housing (1230). The second optical element (1235') is optically coupled to the first optical element (1235). The laser head (1200) further includes a containment plenum (240) coupled to the housing (1200). The containment plenum (240) is optically coupled to the second optical element (1235') to receive the laser light from the second optical element (1235'). The containment plenum (240) is adapted to confine the material and to remove the material from the interaction region resulting from irradiating the structure with the laser light.
