High gain holmium-doped fibre amplifiers.
We investigate the operation of holmium-doped fibre amplifiers (HDFAs) in the 2.1 µm spectral region. For the first time we demonstrate a diode-pumped HDFA. This amplifier provides a peak gain of 25 dB at 2040 nm with a 15 dB gain window spanning the wavelength range 2030 - 2100 nm with an external noise figure (NF) of 4-6 dB. We also compare the operation of HDFAs when pumped at 1950 nm and 20...
متن کاملGain-switched holmium-doped fibre laser.
We demonstrate the first gain-switched, singly doped, single-mode holmium-doped silicate glass fibre laser that operates at 2.106 microm. Using a gain-switched 1.909-microm thulium-doped fibre laser as the pump source, output pulses of energy 3.2 microJ and pulse duration of 150 ns were generated at 80 kHz and slope efficiency of 44%. Pulse stacking within the holmium-doped fibre laser resulted...
متن کاملHigh Gain Erbium Doped Fiber Amplifiers
Performance improvements by using an isolator as an amplified spontaneous emission suppressing component within erbium-doped fibers are evaluated. Simultaneous high-gain and near-quantum-limited noise figures can be obtained by such a scheme. The noise figure improves for input signal powers below -5 dBm and an improvement of 2.0 db with a simultaneous gain increase of 4.1 dB is measured relati...
متن کاملComparative Gain Analysis of Erbium and Ytterbium Doped Optical Fibre Amplifiers
In the present work, gain of EDFA (Erbium Doped Fibre Amplifier) and YDFA (Ytterbium Doped Fibre Amplifier) are analyzed based on their performance parameters. The effects of pump laser power, length of doped fibre that used for amplification and the wavelength of the input signal on the gains of the optical amplifiers is examined. EDFA exhibits maximum gain of 48db around 1550nm regions with p...
متن کاملDevelopment of resonantly cladding-pumped holmium-doped fibre lasers
The resonant pumping of holmium fibre lasers provides a fibre laser platform capable of addressing a wide range of applications that benefit from operation at wavelengths beyond 2.1 μm. This architecture can provide laser devices that promise high efficiency sources in the 2.1 μm spectral region with excellent beam quality and power scalability. This paper presents our recent results of resonan...
