Double Cladding Fiber Laser and It's Application in Military

Highpower double cladding fiber laser is a new type of solidstate laser with extensively investigation in the word in recent years. The advantages of fiber laser include larger surface area for heat diffusion, good beam quality and compact structure. In this paper, the fundamental principle, main characteristics and recent progress of fiber laser are reviewed. On this basis, the experimental results of fiber laser with semiconductor laser pumping techmology and fiber coupling technology at Shanghai Institute of Optics and Fine Mechanics are introduced in detail. The application of highpower fiber laser in military, especially, the possibility of fiber laser using as space laser weapon are analyzed. Finally, the methods to get highpower fiber laser with singlemode output are discussed.
