A device of green laser irradiation therapy in blood vessel

摘要

A semiconductor green laser irradiation therapy device comprises a laser generator (3) which consists of a semi-conductor laser (4), a pump, a frequency multiplication crystal (5), a focus lens (6) and a corrective lens (7), which are assembled sequentially along light path in a cavity of the laser generator (3). Infrared laser which wavelength is 808 nm emitted by laser (4) is transferred via pump and frequency multiplied into green laser which wavelength is 532 nm, and then coupling output through optical fiber coupler (8). The green laser can kill effectively some special pathogenic bacteria and virus in body blood, and activate superoxide dismutase of cell, promote metabolism of cell membrane, therefore the immunity of the human body is improved.
