It’s a 200mW Ytterbium-Doped Fiber Amplifier. Its pigtail fiber type is PM980 Polarization-maintaining fiber. The default working wavelength is 1030nm~1070nm. The wavelength can be customized according to customer needs. It supports ACC Automatic Pump Current Control, APC Automatic Power Control two working modes. This YDFA is controlled by buttons, and software control function can also be added. Let’s check it now.
Left and right buttons can switch between ACC and APC working modes.
Press the middle square button to enter the setting state.
The up and down buttons adjust the current/power size.
Press the middle square button again to confirm the setting value and exit the setting state.
Finally, the key is turned to ‘ON’, the ‘Active’ indicator lights up, and the fiber amplifier starts to work.
The test data of YDFA-23-PM.
This is the relationship between current and output power at 0dBm@1064nm signal input.
Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with a semiconductor laser, and is used to amplify laser signals in the 1030~1100nm band. PM980 polarization-maintaining fiber output, 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. A more compact modular YDFA is also available, which is convenient for users’ system integration. Both desktop YDFA and modular YDFA can support PC software control and serial port command control.
