title = "Rapid decay of type-II femtosecond laser inscribed gratings within Q-switched Yb3+-doped fiber lasers",
abstract = "Fiber lasers that utilize femtosecond (fs) laser inscribed type-II fiber Bragg gratings within the active medium are known to produce stable output powers in excess of 100 W during continuous-wave operation. However, here we show that the gratings undergo rapid annealing when employed as high reflectors in pulsed Q -switched fiber lasers operating at average power levels of less than 0.5 W. We demonstrate that a combination of a high population inversion and a high optical field seems to drive this annealing process and point out similarities to photodarkening.",
