The majority of optical fibre now installed in Europe and North America operates in the second telecommunications window, centred at 1.32 microns. In this region, fibre loss reaches one of its minima and chromatic dispersion is negligible. Unlike tra

In the medical field high power fibre-coupled AlGaAs diode lasers operating around 800nm are already making an impact in surgery but for more specialised applications high powers at other wavelengths are required. It is an attractive idea to develop

The operation of a short-pulse, Q-switched, neodymium-doped fiber laser operating at 1.054µm is described experimentally and theoretically. The laser is efficiently pumped with a single-stripe AlGaAs laser diode and emits >1kW pulses. It is seen tha

Q-switching of fibre lasers is an attractive means of converting the relatively low CW power of pump laser diodes into short, high intensity pulses for use in time-resolved sensor systems. Peak powers of 100W at 1.06µm with 15ms duration have previo

Fiber lasers are normally considered to be low-power devices and not competitive with diode-pumped Nd:YAG lasers. However, by employing special glass fiber technology and a novel inner-cladding geometry we demonstrate here a Nd3+-doped single-mode fi

An Nd3+-doped compound-glass fibre laser pumped by a 3W AlGaAs laser diode array is employed as pump source for an Er3+/Yb3+ optical fibre power amplifier. An amplifier gain of 45dB and output signal powers in excess of +20dBm are demonstrated.

Efficient energy transfer has been demonstrated in an Er/Yb co-doped phosphorus doped silica fiber for the first time. This has indirectly allowed the use of reliabIe, high power AlGaAs diode laser arrays as the semiconductor pump source through the

Beam expanders are required for in-line fibre devices such as connectors and power splitters. Such expansion has generally relied on a lens to achieve the necessary beam size. In this letter we demonstrate a rugged alternative approach which is based
