1. A wireless power transmission system comprising:
(i) a laser adapted to emit a beam;
(ii) a power monitor configured to provide an indication of the optical power of said beam;
(iii) an external enclosure comprising an optical window configured to transmit said beam out of said external enclosure;
(iv) an internal enclosure within said external enclosure, comprising:
said laser;
said power monitor; and
internal walls, at least a major part of which have beam blocking properties, being at least one of (a) opaque, (b) partially transmissive having an optical density of at least 0.5, or (c) diffusive, said beam blocking part of said walls being configured to essentially absorb or diffuse at least part of said beam, or a reflection of said beam caused by an object inserted into the beam, if said part of said beam or said reflection of said beam is directed onto said beam blocking part of said walls, such that no part of said beam or said reflection of said beam can be directed out of said enclosures other than through said optical window;
(v) a beam deflection unit; and
(vi) a control unit configured to control said laser,
wherein said system further comprises a detection unit configured to provide information enabling an indication of damage to said optical window of said external enclosure, said control unit configured to respond to said indication by causing a modification of a configuration of said system.
