Metastable-state lifetime of erbium ions measured in the fiber propagation direction: Expansion of measurable fiber length

Mami Nakandakari, K. Kuroda, Yuzo Yoshikuni

Abstract We report the measurement of the metastable-state lifetime of erbium ions doped in a fiber. We apply the pump–probe technique with a wavelength-tunable laser array. This technique allows us to measure the lifetime through delayed absorption in the fiber propagation directions. By tuning the wavelength of the pump–probe pulse pairs to a low absorption wavelength, the lifetime of the metastable state is successfully measured in a 5-m-long fiber. The lifetime is determined to be 10.0 ms, which agrees well with previously reported values.

Investigation of non-linear energy transfer dynamics of erbium in yttrium aluminum garnet (Conference Presentation)

Christian Vega, Ramesh K. Shori, Oscar M. Stafsudd

Yttrium Aluminum Garnet (YAG) crystals doped with Erbium have posed an interesting position in the field of rare earth solid state lasers as they possess the property of self-saturation, in which the upper energy level in a laser has a much shorter lifetime than that of the lower level.The non-linear energy transfer dynamics of Er:YAG are modeled under high resonant pump conditions. Specifically the multi-photon effect known as excited state absorption (ESA) is modeled by measuring the cross section in a single crystal Er:YAG sample utilizing a pump and probe technique. The measured ESA cross section is then included in the rate equation modeling that has typically been ignored such an effect when modeling the non-linear ion to ion interactions. By pumping with selective resonant pumps, the interaction dynamics of the upper and the lower laser levels in the Erbium ion reveal the contributions of the non-linear energy transfer mechanisms towards the populations of the levels respectively. This thesis work shows the added accuracy of the rate equation modeling by its inclusion of the measured ESA cross-section and its effect on the population evolution in the Er:YAG system. The model will be tested with measurements made with select Er:YAG crystals being pumped by combinations of resonant infra-red lasers with a chopper spinning at a rate on the order of magnitude of the lower lasing level lifetime.
