Overview
FT-4159 (2+1)x1 PM Pump and Signal Combiner
The FT-4159 is a (2+1)x1 polarization-maintaining pump and signal combiner for high-power fiber lasers and fiber amplifiers. It combines two pump lasers with a seed signal, achieving pump efficiency above 90% and extinction ratio of at least 18 or 16 dB at 23 C by configuration. Signal insertion loss is at most 0.5 or 0.7 dB, return loss exceeds 45 dB, and each pump port handles up to 50 or 100 W. Pump wavelength spans 800 to 1000 nm; signal wavelength spans 1030 to 1080 nm or 1450 to 1600 nm. Seven package options (D1 through D7) plus custom housings are available. Operating temperature is -5 to +70 C; storage is -40 to +85 C.
