Power scaling of Tm^3+ doped ZBLAN blue upconversion fiber lasers: modeling and experiments
Applied Physics B, 2006Co-Authors: G. Qin, A. Shirakawa, S. Huang, Y. Feng, M. Musha, K.-i. UedaAbstract:Power scaling of Tm^3+ doped ZBLAN blue upconversion fiber lasers was investigated by a simple model. Based on our experimental results on blue fiber lasers, we discuss the effects of photodegradation and photocuring, fiber length, the reflectivity of the Coupler Mirror and fiber core diameter on further enhancement of blue fiber laser, respectively. The optimal parameters (including fiber length, fiber core diameter and the reflectivity of the Coupler Mirror) for the operation of high power (>1 W) blue fiber laser were presented through simple numerical simulations, which are valuable for the future design of high power blue upconversion fiber laser.

Multiple-wavelength up-conversion laser in Tm/sup 3+/-doped ZBLAN glass fiber
IEEE Photonics Technology Letters, 2005Co-Authors: Shenghong Huang, Yan Feng, A. Shirakawa, K.-i. UedaAbstract:In this letter, we report on a multiple-wavelength up-conversion laser in Tm/sup 3+/-doped ZrF/sub 4/--BaF/sub 2/--LaF/sub 3/--AlF/sub 3/--NaF glass fiber pumped by an 1120-nm fiber laser. Single-wavelength, two-wavelength, and three-wavelength up-conversion lasers can be obtained by adjusting the distance between the Coupler Mirror and the fiber end, which is attributed to the frequency-filter effect in the etalon composed of the Coupler Mirror and the fiber end. The effects of the pump power on the performance of dual-wavelength laser were also discussed.

Spectral narrowing and locking of a vertical-external-cavity surface-emitting laser using an intracavity volume Bragg grating
IEEE Photonics Technology Letters, 2006Co-Authors: S. Giet, Handong Sun, Stephane Calvez, Martin D. Dawson, Soile Suomalainen, A. Harkonen, Mircea Guina, Oleg G. Okhotnikov, M. PessaAbstract:We report the use of a volume Bragg grating as an output Coupler Mirror to improve and stabilize the spectral characteristics of 1058-nm vertical-external-cavity surface-emitting laser which is thermally managed using an intracavity diamond heatspreader. Spectrally narrow and locked emission with up to 645mW of TEM0,0 output power is demonstrated
