Abstract: |
A liquid leading pump beam method and device belongs to field of optics and laser photoelectron technique. It includes pumping light source, optical coupling device, liquid leading device and fiber. Thereinto: the optical coupling device receives the pumping light omitted by the pumping light source; liquid nozzle, the pumping beam coupled by the optical coupling device is coupled with liquid column spurted by the liquid nozzle; the central line of cooling fluid collector is aimed at the central line of the liquid nozzle; return flexible hose and liquid-in end are connected with the cooling fluid collector; radiator and circlulating pump are in series, the liquid-in port of the radiator and the liquid-out port of the return flexible hose are connected, the output end of the circlulating pump is connected with the lower end of the liquid nozzle; the liquid nozzle, the cooling fluid collector, the return flexible hose, the radiator and the circlulating pump are in series to form a liquid leading device. The invention resolves the high power pumping problem in solid laser and fiber laser, and the output power of laser can be increased, stability and reliability of laser system can be guaranteed. |
