Holmium-doped ZBLAN fiber has proven to be an efficient high gain material in the 1.2 µm region. In this paper, single-mode fiber lasers and amplifiers at 1178 nm, 1190 nm, and 1200 nm are reported. Over 2 watts of continuous wave output power was achieved with a 10-cm long gain fiber.
A fast method is introduced to model high power, continuous wave Yb-doped fiber lasers. Excellent agreement with measurements is obtained for up to 708W output power within 5 minutes of computation on a desktop computer.
The effect of mode instabilities has become a strong limitation for the average power scaling of fiber lasers and amplifiers with nearly diffraction-limited beam quality. In this contribution it is shown that the output average power of rod-type fiber amplifiers can be efficiently increased well beyond the threshold of mode-instabilities. This way a new average output power record of 2 kW, with an...
We describe the performance of an optimized high-temperature DS-DBR laser used as an uncooled WDM source. Constant wavelength output with less than 6GHz error without mode-hopping is shown for C-band channels from 70–90 °C.
We report a high power Tm-doped fiber laser pumped by a 1173 nm Raman fiber laser. The slope efficiency is 47%, the maximum output power is 46 W and can be scaled to higher power.
We demonstrated a high-power single-frequency, single-polarization, thulium-doped all-fiber MOPA system. The linearly-polarized thulium-doped fiber MOPA yielded 192 W of single-frequency output at central wavelength of 2001 nm with a polarization extinction ratio of >15 dB.
The scaling of the average output power of a single fiber laser emitting diffractionlimited beam-quality is limited by the onset of mode instabilities. The combination of several emitters working below their mode instability threshold is an efficient way around this challenge. In this contribution a robust and compact setup is presented, which employs a multicore fiber with four signal cores. An average...
