The YAR-LP-SF Series is a line of linearly polarized (LP) single frequency (SF) single-mode fiber amplifiers that operate from 1030 to 1070 nm. The series includes 1 to 50 W versions and has a typical bandwidth of 10 to 20 nm (depending on output power) which allows tunability of the input signal for exact wavelength matching. Amplifier input and output are provided by a 1-2 meter optical fiber cable with connectors at the input and a beam collimator (standard beam diameter is 1 mm) at the output. The standard amplifier has a 25 dB input optical isolation and less than -60 dB residual pump power at the input and output ports. The typical extinction ratio is ~20-23 dB. An optional output free space optical isolator is also available on request.
The amplifiers are available in a 19” rack mount unit and are ideal for a variety of applications including coherent beam combining, detection systems, sensing and other applications. These amplifiers do not need water-cooling or replacement parts and requires only a 110/220V AC power source to provide amplification for your low power signal. They utilize broad stripe (1x100 µm) pump diodes with a nominal wavelength of 965 nm. Estimated diode lifetime for these diodes is more than 100,000 hours at 25°C.
