Townes demonstrated a working device that focused “excited” ammonia molecules in a resonant microwave cavity, resulting in the emission of a pure microwave frequency. Townes named this device a maser, short for “microwave amplification by the stimulated emission of radiation.” Independently, Aleksandr Mikhaylovich Prokhorov and Nikolay Gennadiyevich Basov of the P.N. Lebedev Physical Institute in Moscow described the theory of maser operation. Their collective work earned them the 1964 Nobel Prize for Physics.

How Fiber Lasers Work

The Birth of the Laser Beam

At the core of fiber laser cutting machines is a technology known as fiber laser. This technology manipulates a beam of light to cut materials with extraordinary precision. Here’s how fiber lasers work:

  2. Amplification of the Laser Beam: As the light source travels through the fiber, the light beam undergoes total internal reflection and amplification. Reflectors at the ends of the fiber further intensify the laser beam.

The Journey of the Laser Beam

Once the laser beam is generated, it needs to be precisely guided to the cutting head through a series of meticulously arranged optical components. This process includes:

  1. Guiding the Beam: Mirrors and lenses work in tandem to guide the laser beam to the cutting head.
  2. Focusing the Beam: At the cutting head, the laser beam is finely focused onto the material to be cut.

The Cutting Process

Once the laser beam is focused onto the material, the cutting process begins. This process includes:

  1. Heating the Material: The high energy of the laser beam rapidly heats the material to its melting or vaporization point.
  2. Removal of Material: An auxiliary gas, often high-purity oxygen or nitrogen, accompanies the laser beam. This gas aids in ejecting molten or vaporized material from the cut and, in some cases, may also enhance the cutting process by reacting with the material.
