Laser modules and components, Optical Amplifiers

Designed with all-polarization-maintaining fiber laser architecture, the single frequency fiber amplifier can accomplish multi-stage optical amplification of narrow linewidth (kHz) single-frequency signals to provide high power output, achieving near diffraction-limited beam quality while maintaining high polarization extinction ratio (PER). This high power single frequency PM fiber amplifier integrates stimulated Brillouin scattering (SBS) suppression technology and polarization maintaining technology, capable of providing a broad selection of output power from 100mW to 100W satisfying the needs of various applications.

The CK series high power single frequency fiber amplifier is typically designed for ultra-narrow linewidth single frequency laser source such as fiber lasers made on the basis of DFB or DBR principle. The fiber amplifier is capable of amplifying low power optical signal of kHz level up to 100W output power, while maintaining the spectral property of the input signal.

Utilizing high power and high performance multi-mode pump source, along with double-cladding fiber amplification technology and integrated design of all-polarization-maintaining structure, this fiber amplifier can realize continuous tuning of output power. The CK series fiber amplifier is a Turn-Key system that adopts microprocessor to control, coupled with laser switch at front panel, LCD display to show the power state, and the knob for output power adjusting.
