2μm Band 25dBm TDFA Fiber Amplifier

-

 Today we introduce a 25dBm thulium-doped fiber amplifier. This product uses advanced semiconductor laser pumping and rare earth gain fiber, combined with a dedicated integrated circuit chip, to achieve high stability, high gain, and low power consumption. The laser is coupled and output through a single-mode fiber, and the method of use is simple. It can be widely used in tests and experiments in the fields of optical communication, fiber laser, and fiber sensing.

In optical communications, fiber amplifiers can be used to amplify and regenerate long-distance optical signals; in optical networks, fiber amplifiers can be used to improve the transmission performance of the network and expand the coverage of the network.


This product is a desktop model with a touch screen on the front. The working mode can be set to ACC / APC.
In ACC (Automatic Pump Current) mode, the working current can be set. In APC (Automatic Power Control) mode, the output power can be set.
At the same time, the current working mode, current working status, working current, output power, temperature and other data are displayed on the screen. Users can also control TDFA through software.

Both desktop and modular TDFA can support host computer software control or serial port command control. Users can choose the TDFA model with appropriate parameters according to their own needs to achieve the best amplification effect. We can also provide customized products according to the specific needs of customers.



Thulium-doped fiber amplifier (TDFA for short) can be used to amplify 2μ band laser signals in the power range of -10dBm~+10dBm. The saturated output power can reach up to 40dBm, and it is often used to increase the emission power of laser light sources. Desktop TDFA is convenient for experimental operation. Users can set parameters through the front panel. It can also provide more compact modular products to facilitate system integration.

The test report of this 25dBm TDFA.

Fiber-laser in-band pumping enables novel 2 µm high-power short-pulse laser

Highly efficient high-power short-pulse lasers in the 2 µm wavelength range based on thulium (Tm3+)-doped materials have a variety of applications that include materials processing (such as polymer-to-metal joining), lidar, mid-infrared optical parametric oscillators (OPOs) that produce wavelengths up to 12 μm, and mid-IR supercontinuum generation. They also would enable direct coherent soft x-ray generation via high-order harmonic generation (HHG). For these applications, a light source with much higher conversion efficiency, average power, pulse energy, and shorter pulse duration is desirable. Now, Masaki Tokurakawa and colleagues at the Institute for Laser Science, University of Electro-Communications (UEC; Tokyo, Japan) have developed novel 2 µm high-power short-pulse lasers based on new technique of fiber-laser in-band pumping at 1611 nm and Kerr-lens mode locking with a new Tm-doped gain medium provided from the University of Hamburg by researcher Christian Kränkel.1, 2 ...
