Laser generation importing device applied to human body

A laser generation importing device adapted to a human body, comprising

• tunable laser device capable of emitting laser, wherein the tunable laser device comprises
• a semiconductor chilling plate capable of adjusting temperature, and a laser emission array on the semiconductor chilling plate, wherein the laser emission array comprises multiple independent laser units capable of emitting different wavelengths;
• wherein the wavelength difference of the wavelengths emitted by two laser units which emit adjacent wave bands is less than or equal to the greatest adjustment wavelength of the semiconductor chilling plate;
• and
• multiple laser units are connected to a same power source in parallel via wires, and each laser unit is provided with a switch which can independently control the opening and closing of the laser unit,
• wherein the semiconductor chilling plate, the multiple laser units and a liquid cooling metal sheet are all encapsulated in a sealed box, and the sealed box is provided with multiple light emitting holes configured to output light emitted by the laser units,
• the sealed box is made of thermal insulation materials, thereby further reducing a coding and heating amount, and realizing a precise control and energy conservation, the tunable laser device is connected with a beam combiner, and multiple
• extracted optical fibers led out via the multiple light emitting holes are coupled and converged into one output in the beam combiner,
• the light emitted by one of the laser units is transmitted to a coupler via a lens, the coupler then transmits the light to one of the extracted optical fibers, and the extracted optical fiber introduces the light into the beam combiner, the coupler is arranged on one of the light emitting holes, and then the coupler is in direct butt joint with the extracted optical fiber.
