Overview
FT-138 (2+1)x1 Pump and Signal Combiner
The FT-138 is a (2+1)x1 pump and signal combiner that couples two pump lasers with a seed signal for high-power fiber lasers and fiber amplifiers. Built with air-clad technology for robust power delivery, it reaches pump efficiency above 90%, 93% or 95% by configuration. Signal insertion loss is below 0.5 dB, return loss above 45 dB, and total handling power comes in 50, 100 and 200 W ratings. Pump wavelength spans 800 to 1000 nm; signal wavelength spans 1030 to 1080 nm or 1450 to 1600 nm. PM versions reach at least 18 dB extinction ratio. Packages D1 through D7, bare-fiber or 900 micron loose-tube pigtails, and 0.75 or 1 m fiber lengths are available, with custom configurations on request.
