It's a high power Ytterbium-doped optical amplifier, its output power is 37dBm. And high power YDFA built-in 3 cooling fans. The software control function can be customized, and the default is button control. The current working mode, current and output power are displayed on the front display. https://www.civillaser.com/index.php?main_page=product_info&products_id=3049

1. Ytterbium-doped Fiber Amplifeir 37dBm SM
Fiber Laser Source Benchtop
Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with
semiconductor laser, which is used to amplify laser signals in the 1030~1100nm band, Hi1060
single-mode fiber output, the output power is continuously adjustable, with high gain and low
The advantage of 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.
What we are going to talk about today is 37dBm 5W single-mode YDFA and 40dBm 10W PM
YDFA. First up is 5W SM YDFA. This fiber amplifier built-in 3 cooling fans.

2. The following is 40dBm PM YDFA. It's a high power polarization maintaining ytterbium-doped
optical amplifier. Civil Laser's 10W high power YDFA include a 'Monitor' fiber.

5. CivilLaser's EDFA and YDFA both support APC and ACC working modes, and both modes can be
switched. The software control function can be customized, and the default is button control. The
working current or output power can be adjusted by the button.
