Efficient, low noise grating-feedback fibre laser doped with Er3+:Yb3+
Single-frequency Er3+-doped Fabry-Perot fiber lasers using fiber-grating Bragg reflectors are emerging as interesting alternatives to distributed-feedback (DFB) diode lasers for use in future high-capacity wavelength-division multiplexed (WDM) communication systems.

Fiber lasers are only robustly single frequency provided that the laser length is reduced to a few centimeters to increase the axial mode spacing and the grating bandwidth is kept below approximately 0.2 nm. It is also necessary to keep the Er3+ concentration low to avoid a reduction in efficiency by ion-pair quenching, and this combination of factors means that the pump absorption in the laser length can be as low as a few percent. Hence the slope efficiency of these lasers is very low. It is possible to increase the output power by using the residual pump power to pump an erbium-doped fiber amplifier (EDFA) following the fiber laser.

Abstract
Single-frequency Er3+-doped Fabry-Perot fiber lasers using fiber-grating Bragg reflectors are emerging as interesting alternatives to distributed-feedback (DFB) diode lasers for use in future high-capacity wavelength-division multiplexed (WDM) communication systems. They are fiber compatible, scaleable to high output powers (>1W), and have low noise and kilohertz linewidths. Fiber lasers are only robustly single frequency provided that the laser length is reduced to a few centimeters to increase the axial mode spacing and the grating bandwidth is kept below approximately 0.2 nm. It is also necessary to keep the Er3+ concentration low to avoid a reduction in efficiency by ion-pair quenching, and this combination of factors means that the pump absorption in the laser length can be as low as a few percent. Hence the slope efficiency of these lasers is very low. It is possible to increase the output power by using the residual pump power to pump an erbium-doped fiber amplifier (EDFA) following the fiber laser. However, the presence of the amplifier amplified spontaneous emission (ASE) increases the output noise. In addition, it has been reported that these lasers are susceptible to strong self-pulsation.
