1.5 μm Single Frequency, PM, Fiber Amplifiers (Gen. II)

1.5 μm Single Frequency, PM, Fiber Amplifiers (Gen. II)

The Nufern NuAMP PSFA family of high power, polarization maintaining fiber amplifiers offer the broadest operating wavelength range in the industry. They are specifically designed to operate in conjunction with ultra narrow linewidth, single frequency seed lasers based on distributed feedback (DFB) fiber lasers or solid state technologies. Capable of amplifying low power input signals with kHz linewidth to 2, 5 and 10 W of power, these monolithic amplifiers use large mode area fiber technology to overcome non-linearities such as stimulated Brillouin scattering (SBS) and maintain critical seed laser characteristics such as narrow linewidth and relative intensity noise (RIN). The series includes input isolation (>30 dB at RT) and input/output interlocks to prevent system failure due to loss of signal and high back reflection, and to protect the seed source (response time of <10 msec).
