    • 2um Single Frequency Polarization Maintaining Thulium Doped Fiber Amplifier (TDFA) 1950-2050nm TDFA-1W-FA-PM

    Idealphotonics Thulium-doped Benchtop Single-Frequency Polarization-Maintaining Fiber Amplifier is a power amplifier specially designed for ultra-narrow linewidth, single-frequency signal light (such as fiber lasers made based on DFB and DBR principles). This amplifier can amplify low-power optical signals of the kHz level to an output power of up to 50W, and can well maintain the spectral characteristics of the input signal light. Our amplifier uses a high-power, high-performance multi-mode pump source, double-clad fiber amplification technology, an integrated design of a fully polarization-maintaining structure, and continuously adjustable output power. The benchtop fiber amplifier is a complete Turn-Key system, which is internally controlled by a microprocessor. The front panel is equipped with a laser start switch and a power status LCD display, as well as an output power adjustment knob. Benchtop polarization-maintaining fiber amplifier (TDFA) can be widely used in scientific research, coherent synthesis, coherent detection sensor systems, etc.
