Laser marking machines currently on sale are divided into three categories according to laser categories, namely CO2 laser marking machines, UV (ultraviolet) laser marking machines and fiber laser marking machines.
What are the specific differences between these three types of laser marking machines and how to choose the marking machine that suits you when purchasing? This article will sort it out for you in detail and answer them one by one.
The main differences between the three are as follows:
Wavelength
CO2 Lasers: Emit infrared light with a wavelength typically around 10.6 micrometers.
UV Lasers: Emit ultraviolet light with wavelengths ranging from 100 to 400 nanometers.
Fiber Lasers: Emit light in the infrared spectrum, commonly around 1.06 micrometers.
Medium
CO2 Lasers: Use a gas mixture, typically carbon dioxide, nitrogen, and helium, as the laser medium.
UV Lasers: Use crystals, semiconductors, or gases as the laser medium. Examples include excimer lasers and dye lasers.
Fiber Lasers: Use optical fibers doped with rare-earth elements, such as ytterbium, erbium, or neodymium, as the laser medium.
Application
CO2 Lasers: Commonly used in cutting, engraving, and marking materials like wood, plastic, and metal. They are also used in medical procedures and scientific research.
UV Lasers: Often used in applications requiring precise and high-energy laser beams, such as semiconductor manufacturing, micromachining, and medical procedures like eye surgery.
Fiber Lasers: Widely used in industrial applications for cutting, welding, and marking metals. They are also employed in telecommunications, sensing, and medical devices.
Absorption
CO2 Lasers: Well-absorbed by organic materials like wood and plastic.
UV Lasers: Efficiently absorbed by many materials, especially those with high optical absorption in the UV range.
Fiber Lasers: Can be absorbed by metals, making them effective for metal processing applications.
Output Power
CO2 Lasers: Can achieve high output powers, making them suitable for industrial applications.
UV Lasers: Variable output powers depending on the specific type and application.
Fiber Lasers: Capable of high power output, particularly in metal processing.
Precision
CO2 Lasers: Provide good precision for cutting and engraving applications.
UV Lasers: Offer high precision, making them suitable for microfabrication and delicate processes.
Fiber Lasers: Known for their excellent beam quality and precision, especially in metalworking applications.
Cost
CO2 Lasers: Generally more cost-effective for certain cutting and engraving applications.
UV Lasers: Can be more expensive, especially for high-powered and specialized applications.
Fiber Lasers: Competitively priced and offer cost advantages in metal processing applications.
From the above differences we can see that factors such as material type, required accuracy and cost considerations need to be taken into consideration when choosing the right laser marking machine.
