Frequency Domain Spectroscopy in Rare-Earth-Doped Gain Media

Emir Salih Magden, Patrick T. Callahan, Nanxi Li +6 more

Many spectroscopic techniques today rely on time-resolved measurements under short excitation pulses. Instead of using a chopped pump excitation, or ultrafast optical pulses, we expand on and apply the previously developed set of frequency domain methods to analyze the population level dynamics in rare-earth-doped media. By identifying the full frequency response of the gain medium, this method can accurately yield excited state lifetimes and can also be used to estimate transition cross-sections. The accuracy of the frequency domain methods are verified with Er3+-and Tm3+-doped fibers, and an Al2O3:Tm3+waveguide, recovering similar results as reported by time-resolved techniques. The complete frequency domain model presented here can be used in characterization of novel optical gain media, and can provide insights into population dynamics in solid state amplifiers and lasers.

Low temperature study of rare earth doped glasses

Casey L. Richardson

In this paper, we present a low-temperature study of rare earth doped glasses, which are important for creating compact, efficient gain media. We resolved effective Stark components of erbium doped glasses by analyzing their absorption cross sections at T=293K and T=110K. Using these Stark energy levels and the McCumber theory, we calculated the radiative lifetime of the I/-I/ transition in erbium. Our calculated lifetime agrees with the measured lifetime for this transition better than previously accepted methods.
