Laser source operation technology
Let's start with the fact that fiber lasers belong to the solid-state type. Optical fiber acts as the working medium instead of a crystal.
The fiber is made of silicon or phosphate glass with ytterbium doping. Such a "cable" effectively dissipates heat, that is, heats up less.
The laser source cooling system is a chiller (water cooling).
The laser source consists of (simplified):
1. Diode pump lamps
2. Optical modulator
3. Optical fiber connector
4. Sensors
5. Optical isolator
Principle of laser source operation:
• Pumping is performed in parts using LEDs that emit light with a specified wavelength.
• Collection and transfer of light into optical fiber. For this, the emitter has a connector. It collects light from several diodes and directs it into the optical fiber.
• Passage of light beam through optical fiber. After collection, light enters the output optical fiber. The fiber is coated with a shell that reflects light back and prevents it from scattering.
• Stimulated emission. Light hitting the ytterbium fiber excites its electrons, creating an amplification medium. When equilibrium is reached between excited and calm electrons, a laser beam is formed.
