Ytterbium-doped Fiber Amplifier for 1.0um

Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with a semiconductor laser to amplify laser signals in the 1030~1080nm band, the output power is continuously adjustable, and has the advantages of high gain and low noise. The desktop YDFA is convenient for experimental operation, and the user can adjust the pump current and output power through the buttons on the front panel. It also provides a more compact modular YDFA, which is convenient for users’ system integration. Both desktop YDFA and modular YDFA can support host computer software control and serial command control.

*Note 1:

  • ACC mode: Automatic current control: the EDFA pump working current is set by the user and automatically locked by the EDFA to achieve a constant pump current. When the input optical power fluctuates, the output power will also fluctuate accordingly, which is applicable to all EDFA models.
  • APC mode: Automatic power control mode, where the user sets the signal light output power of the EDFA. Based on the output power monitored by the PD, the EDFA automatically controls and adjusts the pump current to achieve stable output signal. In APC mode, the user can adjust the output power within a range of 10% to 100% of the maximum output power. The advantage of APC mode is that when the input optical power fluctuates, EDFA will minimize the fluctuation of output power as much as possible
