High-Power Photonic Crystal Fiber Lasers
The use of optical fiber has expanded dramatically in recent years. Arising from a technology strongly focused on telecommunications, fiber now may be found in such diverse fields as biotechnology, astronomy and medicine. One of the fastest growing and most promising applications of optical fiber is in high-power fiber lasers. In the past few years, fiber lasers have evolved from low-power systems for niche applications into challengers to the traditional high-power industrial lasers for...
