All-fiber, single-mode spectral beam combining of high power Tm-doped fiber lasers

Yilmaz, S.; Ottenhues, C.; Wysmolek, M.; Theeg, T.; Lamrini, S.; Scholle, K.; Fuhrberg P.; Sayinc H.; Ilday F.Ö.; Neumann J.; Overmeyer L.; Kracht, D. (Optical Society of America (OSA), 2015)

Signal beam combining of Tm-doped fiber lasers can increase the laser output power while simultaneously maintaining the single mode beam quality. We demonstrate an all-fiber integrated dual-wavelength Tm-doped fiber laser ...
Enhanced hole transport in InGaN/GaN multiple quantum well light-emitting diodes with a p-type doped quantum barrier

Ji Y.; Zhang, Z. -H.; Tan S.T.; Ju, Z. G.; Kyaw, Z.; Hasanov N.; Liu W.; Sun X. W.; Demir, H. V. (Optical Society of America, 2013)

We study hole transport behavior of InGaN/GaN light-emitting diodes with the dual wavelength emission method. It is found that at low injection levels, light emission is mainly from quantum wells near p-GaN, indicating ...
