“…The pump power was not increased to a value higher than 20 W during the experiment to avoid isolator damage and fiber breakdown. It is interesting to note that the generation of cascaded SBS pulses in active fiber was previously reported for laser schemes with free-space signal coupling [13]. As far as we know, the instability behaviour associated with the generation of the SBS signal in passive delivery fibers arising from the all-fiber laser format is reported for the first time.…”

In this paper, we present results on the amplification of 2 MHz linewidth nanosecond pulses in a recently developed ytterbium-free erbium-doped large mode area fiber cladding pumped at 980 nm. A record peak power of 4 kW for single-frequency single-mode silica-based fiber sources near 1550 nm is demonstrated. Pulse instabilities arising in an all-fiber laser scheme from stimulated Brillouin scattering are described.

“…Yb-free cladding pumped Er-doped fiber with a core diameter of 20 was used as the active medium of the laser. Similar approach was used in papers [13][14][15][16] Figure 4 (online color at www.lphys.org) Output spectrum of the supercontinuum source written in the multimode fiber in fiber lasers was demonstrated in [18,19]. To Q-switch the Er-doped fiber laser we have used a piece of the heavily Tm-doped fiber with the length of 6 cm between the input Bragg grating and Erdoped fiber [20].…”

For the first time to our best knowledge we have realized all-fiber supercontinuum source based on standard telecommunication multimode fiber. To pump the source Qswitched Er-doped fiber laser was used. The observed spectrum covers the spectral range from 1550 to 2400 nm with the power variation less than two decades. Average power of 0.85 W and pulse energy of 0.19 mJ was measured. Average power versus pump power for Q-switched Er-doped laser (1) and supercontinuum source (2)

“…Previously, such fibers were used in papers [13,14] to obtain continuous wave (CW) and mode-locked oscillation near 1.6 μm. To get Q-switching we have placed a piece of the heavily Tm-doped fiber within the laser cavity [15,16].…”
