All lasers consist of three components:
- An external pump source
- The active laser medium
- The resonator
The pump source guides external energy to the laser.
The active laser medium is located on the inside of the laser. Depending on the design, the laser medium can consist of a gas mixture (CO2 laser), of a crystal body (YAG laser) or glass fibers (fiber laser). When energy is fed to the laser medium through the pump, it emits energy in the form of radiation.
The active laser medium is located between two mirrors, the "resonator". One of these mirrors is a one-way mirror. The radiation of the active laser medium is amplified in the resonator. At the same time, only a certain radiation can leave the resonator through the one-way mirror. This bundled radiation is the laser radiation.
- Monochromatic. This means that the radiation consists of only one wavelength.
- High coherence and thereby phase coincidence.
- The waves of the laser are approximately parallel due to the coherence.
Our laser experts are happy to answer your questions about our products and laser processing. They will help you discover all the possibilities of laser engraving, cutting and marking. Additionally we invite you to see our lasers and applications at one of our demonstration facilities.
