1.0um High Power Single Frequency Polarization Maintaining Fiber Amplifier

The MARS series high power single frequency polarization maintaining fiber amplifiers of Connet are designed specifically for the ultra-narrow linewidth single frequency laser source, such as the fiber lasers based on the principle of DFB or DBR. This kind of amplifier has the capability of boosting the low power optical signal at kHz level up to 100W output power and meanwhile preserves the spectral property of the input signal. The MARS series amplifiers use the high power, high-performance, multi-mode pumps internally, employ the technology of double cladding fiber amplification, and have the integrated design in all polarization-maintaining structure. The output power can be continuously tunable. The MARS series fiber amplifiers are the integral Turn-Key system with the microprocessor inside for controlling. The front panel is equipped with the switch to start the laser, the LCD to display the state of the power and the knob to adjust the output power.

With the extensive experience in handling the double cladding fiber, Connet conducts the proper optimal design for the high power polarization maintaining fiber amplifiers to achieve the high efficiency output and meanwhile suppress the nonlinear effects of the fiber. The unique thermal treatment technology guarantees that the benchtop fiber amplifier can be operated stably for a long time. The high-speed response protection circuit monitors the power of the input and the output signals automatically so that it can cut down the operation of the high power pump in case of the falling off of the input signal to ensure the safety of the whole system.

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