MARS series high power single frequency polarization maintaining fiber amplifiers by Connet are designed specifically for ultra-narrow linewidth single frequency laser sources, such as the fiber lasers based on the principle of Distributed Feedback Bragg Grating (DFB) or Distributed Bragg Reflector (DBR). This kind of a fiber amplifier has the capability of boosting the low power optical signal at kHz frequencies up to 50W output power while preserving the spectral properties of the input signal. 

MARS series amplifiers use high power, high-performance, multi-mode pumps, employ the technology of double cladding fiber amplification, and feature an integrated design in a polarization-maintaining structure. These high power single frequency fiber amplifiers come with a continuously tunable output power.

With the extensive experience in handling double cladding fibers, Connet conducts proper optimal design for high power polarization maintaining fiber amplifiers to achieve high efficiency output and suppress the nonlinear effects of the fiber. 

The unique thermal treatment technology guarantees that this benchtop fiber amplifier can be operated stably for a long time. In order to ensure the safety of the whole system, the high-speed response protection circuit monitors the power of the input and output signals automatically so that it can cut down the operation of the high power pump in case of an input signal fall-off.

MARS series fiber amplifiers are turn-key user-friendly systems with an internal microprocessor for laser control purposes. The front panel is equipped with a switch to start the laser, a LCD to display the state of the power and a knob to adjust the output power.

Connet MARS series high power benchtop polarization-maintaining fiber amplifiers can be widely used in scientific research, coherent beam combining, coherent detection, fiber sensing system, etc.
