Abstract:We have made a compact fiber pulsed source based on a self Q-switched Yb-doped fiber laser with an additional amplification. The output pulse energy of 0.17 mJ has been achieved with a pulse duration of several tens nanoseconds. The repetition frequency of 20 kHz and the maximum average output power of 3 W were observed.Intensity, a.u. Pulse shapes measured on two outputs of the oscillator

We have realized a compact Bragg grating based Ho3+ fiber laser emitting at 2.1 μm with a CW output power of 2 W. The laser is pumped by an Yb3+ fiber laser at 1.12 μm, the latter laser being based on a GTWave active fiber pumped by two semiconductor modules with a maximum power of 25 W at 0.98 μm.
