1.5um High Power Single Frequency Polarization Maintaining Fiber Amplifier

Product Description:

The MARS series high power single frequency polarization maintaining optical fiber amplifiers of Connet  are designed specifically for the ultra-narrow linewidth single frequency laser source, such as  single frequency External Cavity Lasers and fiber lasers based on the principle of DFB or DBR. This kind of amplifiers has the capability of boosting the low power optical signal at kHz magnitude up to 50W output power and preserves the spectral property of the input signal. The MARS series amplifiers use high power high performance multi-mode pump internally, employ the technology of double cladding fiber amplification, and have the integrated design of all polarization-maintaining structure. The output power can be continuously tuning. MARS series fiber amplifiers are 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.

Due to the extensive experience of handling the double cladding fiber, Connet conducts proper optimal design to the high power polarization maintaining fiber amplifiers, thus achieving high efficiency output while suppressing the nonlinear effects of the fiber. The unique thermal treatment technology guarantees that the desktop fiber amplifier can operate stably for a long time. The high-speed response protection circuit monitor the power of input and output signal automatically so that it can cut down the operation of the high power pump in case of the falling off of the input signal, thus ensures the safety of the whole system.

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