Fiber Amplifiers
A fiber amplifier boosts the output power of a laser cavity, utilizing various types of laser sources as previously outlined. The medium employed to amplify the power is an optical fiber doped with rare-earth (RE) ions. The most commonly used configuration in fiber amplifiers is the master oscillator power amplifier (MOPA) architecture, designed to enhance the power of a signal transmitted from a laser (oscillator) by optically pumping an active medium. Amplification occurs solely when the population of atoms in the low energy level is excited (inverted) by a power source (pump) to the higher level; stimulated emission surpasses absorption. Wavelength Opto-Electronic is the partner of HÜBNER Photonics and Cobolt brand of lasers for Singapore, Malaysia, and Thailand.
