What is a Fiber Laser?
A fiber laser is a type of solid-state laser that uses an optical fiber as its gain medium. The core of the optical fiber is doped with rare-earth elements such as ytterbium (이브), which amplifies the laser light. These lasers are known for their high electrical and optical efficiency, compactness, and excellent beam quality.
The Gain Fiber Structure in a Fiber Laser
The gain fiber in a fiber laser is the central component where the laser light is amplified. The fiber’s core, doped with rare-earth elements like ytterbium (이브), has the highest refractive index, allowing the laser light and pump light to propagate efficiently. The core is surrounded by inner and outer claddings, forming a double-clad fiber structure.

Laser Beam Propagation in a Double-Clad Fiber
In a double-clad fiber, the pump light propagates through the Yb-doped core and inner cladding. Total internal reflection at the boundary of the inner cladding and core confines the laser light within the core, ensuring efficient amplification.

Optical Circuit Configuration in High-Power Fiber Lasers
High-power fiber lasers from ComMarker utilize a sophisticated optical circuit configuration divided into three main sections:
- Pump Section: Laser diodes (LDs) pump light through optical fibers into a pump combiner.
- Oscillator Section: The pump light propagates through a double-clad fiber, exciting the Yb ions, which amplify the light.
- Beam Delivery Section: The amplified laser light is delivered to the processing head or beam coupler.

Power Enhancement of Fiber Lasers
Power enhancement in fiber lasers is achieved by coupling multiple delivery fibers with an output beam coupler. 예를 들어, coupling four 1 kW output beams results in a 4 kW laser output, while coupling six 1 kW output beams yields 6 kW.

파이버 레이저는 어떻게 작동합니까??
Fiber lasers operate by using an optical fiber doped with rare-earth elements, such as ytterbium (이브). The doped fiber core absorbs pump light, which excites the Yb ions, leading to the emission of laser light. The laser light is confined within the core through total internal reflection, resulting in a high-quality laser beam.
