Method of compensating the dispersion of fluorine-based fiber lasers in the second optical window |
摘要 |
A method of manipulating a compensation fiber for compensating the high negative dispersion of a fiber laser in the second optical window. The active fiber of the fiber laser is linked to a compensation fiber which consists of a step-index quartz glass core with a sheathing. By doping the compensation fiber sheathing with fluorine in a targeted manner, a positive value is set for the dispersion of the compensation fiber. Subsequent dimensioning of the length of the compensation fiber increases the set dispersion value to the positive dispersion value necessary for complete compensation of the dispersion of the fiber laser.
