Main Types of Lasers
There are three main types of lasers: gas lasers that use gases like carbon dioxide as the active medium; liquid lasers such as dye lasers; and solid-state lasers that use a solid as the active medium.
Gas Lasers
Gas lasers are some of the most powerful lasers available. They are used in medical, industrial, and scientific applications. The most common gas laser is the carbon dioxide laser.
Solid-State Lasers
Solid-state lasers occupy less space than gas lasers and provide cost savings. However, they have lower power and can only cut thin material less than 8mm thick. From a maintenance perspective, solid-state lasers are more cost effective.
Laser Power and Application
The power of a laser plays a key role in determining its effectiveness for processes like welding, cleaning, texturing, cutting, and marking. Lasers with higher power speed up these material processes.
Choosing a Laser
When choosing a laser, factors like wavelength and emission power need to be considered based on the application and processing conditions required. Lasers with the highest market share currently are fiber lasers, CO2 lasers, and solid-state lasers.
