What is a “Laser”

Laser is defined as a high-energy light source emitted by the natural vibrations of atoms (of a gas or solid material) that is able to cut, burn or dissolve.

Laser stands for Light Amplification by Stimulated Emission of Radiation.

Laser type

The most accessible lasers include as below.

  • Fiber Laser: Wavelength 1064nm. Marking processing and cutting processing.
  • CO2 Laser: Wavelength 10.6um. Processing machines, marking application, laser knives.
  • Green Laser: Wavelength 532nm. Soft marking applications for silicon wafers.
  • UV Laser: Wavelength 355nm. LCD marking, repair processing, via hole processing and other micro processing.

Fiber laser

Fiber lasers deliver their energy through an integrated flexible optical fiber. Fiber lasers have a monolithic, entirely solid state, fiber-to-fiber design that does not require mirrors or optics to align or adjust. These features make fiber lasers easier to integrate and operate in production, medical and other laser-based systems.

Fiber lasers are typically smaller and lighter in weight than traditional lasers, saving valuable floor space. While conventional lasers can be delicate due to the precise alignment of mirrors, fiber lasers are more rugged and able to perform in variable working environments.

Suited for the following materials: Most of metals, hard plastic.

Did Front fiber laser marker could cutting metals?
Front fiber laser is lower power (10-50watt). It is not suit for cutting metals. As for 50 watt fiber laser could cut 0.3mm steel.

Co2 laser

CO2 laser are gas lasers that are based on a carbon dioxide gas mixture, which is stimulated electrically. With a wavelength of 10.6 micrometers, they are mainly suited for working on non-metallic materials and on most plastics. CO2 lasers have a relatively high efficiency and feature a very good beam quality. They are therefore the most widely used laser types.

Suited for the following materials: Wood, acrylic, leather, fabric, glass, paper, rubber, stone, etc.

Did Front Co2 laser cutter could cutting metals?
We are using 80-150watt glass sealed CO2 laser. Such a low power laser can not cut metals. If flowing the oxygen with 150watt Co2 laser. It could cut 1mm steel. But that is big damage on laser tube, we don’t suggest doing that.
