1064 50W Fiber Amplifiers

NuAMP 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 line-width (kHz or below), single frequency seed lasers based on distributed feedback (DFB) fiber lasers or solid state technologies. Capable of amplifying low power input signals as low as 1mw up to 50 W of linearly polarized output 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 line-width and frequency stability. The series includes input isolation (≥30 dB at RT) to protect the seed source and various safety interlocks to prevent system failures such as the loss of the input signal or the presence of the high back-reflection.
