The YDFA300P gain can be controlled in automatic current control (ACC) mode via the front panel interface. The pump current of the amplifier is adjustable through the instrument's front panel, allowing the user to vary the gain and output power.
Please refer to Section 1.4.2 of the manual or to the published raw data on the Thorlabs website for the scaling of the output power vs. the input power.

1050 nm Ytterbium-Doped Fiber Amplifier Chapter 2: Safety Chapter 2 Safety Risk of Electrical Shock High voltage inside. To avoid electrical shock, before powering the unit on, make sure that the protective conductor of the 3-conductor power cord is correctly connected to the protective earth contact of the socket outlet.
Test Data Sheet Installation Instructions Prior to using the YDFA300P system, it is highly recommended to clean the input and output bulkheads as well as the connector facets to be connected to the bulkheads. Failure to clean the connectors can result in damage to the internal connectors in the YDFA300 as well as the connectors on fiber patch cables connected to the amplifier.
FC bulkhead connector and the patch cable connector beforehand. Please note that the YDFA300P amplifier requires a minimum input power of -5 dBm (0.3 mW) for stable operation. The amplifier is equipped with internal shutoff mechanism that turns off the output if the input power drops below this level.
1050 nm Ytterbium-Doped Fiber Amplifier Chapter 4: Operation Laser Warning The amplifier generates invisible amplified spontaneous emission (ASE) even without any optical input. The power level of the ASE can be as high as 200 mW. Therefore, all laser safety measures should be followed even if the input light to the amplifier has been disconnected or switched off.
1050 nm Ytterbium-Doped Fiber Amplifier Chapter 5: Remote Operation from Command-Line Interface Chapter 5 Remote Operation from Command-Line Interface The Command Line Interface (CLI) provides the user with a method of controlling the YDFA remotely over the USB interface that is emulating a serial port. A standard terminal program (such as Tera Term) can be used to send commands to the YDFA and receive responses.
Making Safety Interlock Connections The YDFA300P instrument is equipped with a remote interlock connector located on the rear panel. In order to enable the fiber amplifier, a short circuit must be applied across the terminals of the Remote Interlock connector.
Always clean the ferrule end of your fiber patch cables as well as the input and output FC bulkheads prior to inserting the fiber patch cables into the FC bulkheads. Thorlabs offers the FCC-7020 Fiber Cleaning Cloth Spool, which can be used for cleaning the ferrule ends of the patch cables.
