The amplifiers in the Nufem NuAMP PSFA family are high-power and offer the broadest operating range of wavelengths currently available. Designed for polarization and maintenance, they are made to work in conjunction with single frequency seed and narrow line-width lasers based on solid state technologies or DFB fiber lasers.
This family has low power input signal amplifying capabilities to 1W, 5W, 10W and 15W power (with kHz line-width). The fiber technology mode area is large, and used by monolithic amplifiers to overcome non-linearities, such as SBS, and to maintain important seed laser characteristics such as relative intensity noise. Input isolation of >30dB at RT is included with the series, as well as input and output interlocks to protect the system from failing in the event high back reflection or signal loss. The seed source is protected with a response time of <10msec.
