We have designed a high-average-power diode-side-pumped Nd:YAG laser acousto-optically Q-switched at a pulse repetition rate range of 5-20 kHz. Double synchronized Q-switches were used for increasing the hold-off current and obtained more than 200 W average output power at 10 kHz and 110 ns pulse du

✦ Synopsis
All-optical switching devices based on fibre Bragg grating (FBG) structures written on a standard single-mode fibre and in an erbium-doped fibre have been experimentally demonstrated in the third telecommunication window. The switching devices work due to the thermal changes induced by a high-power continuous-wave laser diode. The filters tunability characteristics have been demonstrated for different pump powers (up to 900 mW) and different pump laser wavelengths (at 980 and 1480 nm), presenting different thermal absorption behaviour within different working regimes.
