2um Single Frequency Single Mode Thulium Doped Fiber Amplifier (TDFA) 1900-2050nm TDFA-1W-FA-SM

Idealphotonics Thulium-doped Benchtop Single-frequency Single-mode Fiber Amplifier is a power amplifier specially designed for ultra-narrow linewidth, single-frequency signal light (such as fiber lasers based on DFB and DBR principles). This amplifier can amplify low-power optical signals in the kHz range 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 and double-clad fiber amplification technology, and the output power is continuously adjustable. The benchtop fiber amplifier is a complete Turn-Key system with internal microprocessor control. 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 single-mode fiber amplifier (TDFA) can be widely used in scientific research, coherent synthesis, coherent detection sensor systems, etc.
