Abstract:
1. A hand held laser configured to be grabbed by hand and moved with manual force for treating a skin condition, the laser comprising: a housing comprising a first end, a second end and a cavity therein wherein the cavity includes a substantially light reflective surface and wherein the housing comprises at least one fin extending from an exterior surface of the housing; a flash lamp having a first axis and being retained within the cavity in a first selected position; a laser rod having a second axis and being retained within the cavity in a second selected position and wherein the first axis and the second axis are substantially parallel to each other, wherein as the flash lamp is pumped the laser rod produces a laser beam for treating the skin condition; a stream of cooling liquid circulating within the housing and contacting the flash lamp and laser rod to remove heat that is generated during use; and a stream of cooling gas contacting the housing including the at least one fin such that the cooling gas removes heat generated during use wherein simultaneously removing heat with both the cooling liquid and the cooling gas allows the hand held laser to be continuously used for an extended period of time without having to be deenergized to allow the device to cool.
