What is a fiber amplifier?

A fiber amplifier is a laser system that boosts an optical signal using a doped optical fiber as the gain medium. Unlike traditional lasers, it amplifies an existing seed signal, enabling high output power with excellent beam quality.

What are the main types of fiber amplifiers?

The most common fiber amplifiers are doped with Ytterbium (Yb), Erbium (Er), or Thulium (Tm). Each is optimized for different wavelength ranges and applications, from industrial high-power lasers to telecommunications and sensing.

What are the advantages of fiber amplifiers over other laser technologies?

Fiber amplifiers offer high efficiency, superior beam quality, excellent thermal management, compact form factors, and long-term reliability. Their all-fiber design minimizes alignment issues and enables stable operation in harsh environments.
