| Research Abstract |
It is important for realizing the high-power fiber laser and high-efficient fiber amplifier to clarify the relationship between the optical properties and fictive temperature in rare-earth doped silica glasses. It was found that optical properties, such as, emission intensity, emission lifetime, photodarkening, strongly depend on the fictive temperature. This fact is very informative to improve the performances of fiber laser and amplifier.
