Thulium-Doped Fiber Amplifier (1800-2050nm)

The 2μm Thulium-doped Fiber Power Amplifier (TDFA) can pump a 1mW seed laser to 164mW output, or even larger, to meet the needs of most experimental work.

The key benefits of TDFA include a wide wavelength range, high output power and low noise. The wavelength range covers the power range from -10dBm to +10dBm, and can accept and amplify a variety of laser signals of different intensities. Its maximum saturation output power is up to 30dBm, which can provide a very powerful laser signal.

In addition, the TDFA is designed and manufactured with noise control in mind, so it has low noise characteristics, making it particularly useful in applications where high precision measurements are required.

*Note 1: The standard model is designed according to 1920~2020nm, and users can propose customized wavelengths according to their needs.

*Note 2: ACC mode - Automatic current control: the user sets the working current of the TDFA pump, and the TDFA automatically locks it to realize the constant pump current. When the input optical power fluctuates, the output power will also fluctuate accordingly, applicable to all TDFA models, PA amplifiers only support ACC mode.

APC mode - Automatic power control: the user sets the signal optical output power of TDFA, the PD automatic monitoring and feedback output power, TDFA control and adaptive adjustment pump to achieve the stability of the output signal, the power adjustment range in APC mode is usually 10%~100%. The advantage of APC mode is that when the input optical power fluctuates, the TDFA will reduce the output power fluctuation as much as possible. It is suitable for power type and line type TDFA, but not suitable for low repetition frequency pulse signals.
