Recent developments in rare-earth-doped fibres and fibre lasers
The development of techniques to produce single-mode rare-earth-doped fibres has led to many passive and active (laser) devices based on these fibres including distributed temperature sensors, high-rejection wavelength selective filters, and fibre lasers and amplifiers. The possibilities offered by fibre lasers and amplifiers are particularly exciting since they present a potential technique for achieving compact, tunable, diode-pumped, narrow-linewidth sources which are compatible with optical fibre technology. Recent developments include diode-pumped fibre lasers operating at 1.08µm with C.W. output powers of 6mW and Q-switched (pulsed) operation with output in excess of 13W. Single-longitudinal-mode operation with a linewidth of 1.3MHz has been demonstrated, as has single-polarisation operation with an extinction ratio of 37dB. The extension of these techniques to operation at 1.55µm will find immediate applications in coherent communications system and will be discussed, as will additional active and passive devices including in-line fibre amplifiers and bistable fibre switches

Abstract

The development of techniques to produce single-mode rare-earth-doped fibres has led to many passive and active (laser) devices based on these fibres including distributed temperature sensors, high-rejection wavelength selective filters, and fibre lasers and amplifiers. The possibilities offered by fibre lasers and amplifiers are particularly exciting since they present a potential technique for achieving compact, tunable, diode-pumped, narrow-linewidth sources which are compatible with optical fibre technology. Recent developments include diode-pumped fibre lasers operating at 1.08µm with C.W. output powers of 6mW and Q-switched (pulsed) operation with output in excess of 13W. Single-longitudinal-mode operation with a linewidth of 1.3MHz has been demonstrated, as has single-polarisation operation with an extinction ratio of 37dB. The extension of these techniques to operation at 1.55µm will find immediate applications in coherent communications system and will be discussed, as will additional active and passive devices including in-line fibre amplifiers and bistable fibre switches
