Types of Laser Engravers

Laser engravers come in various types, each with unique characteristics suited for different applications. The two most common types are CO2 lasers and fiber lasers, which differ significantly in their technology, capabilities, and ideal use cases.

CO2 Lasers

CO2 lasers use a gas mixture (primarily carbon dioxide) as the lasing medium and produce a wavelength of 10.6 micrometers in the infrared spectrum.

Key Characteristics

• Versatility: Excellent for engraving and cutting non-metal materials including wood, acrylic, glass, leather, paper, and certain plastics
• Power range: Typically available from 30W to 150W for hobbyist and small business use, with industrial models reaching 400W or more
• Beam quality: Produces a larger spot size, which is ideal for faster processing of larger areas
• Maintenance: Requires regular maintenance including mirror alignment, lens cleaning, and eventual tube replacement

Best Applications

• Cutting and engraving wood products
• Acrylic fabrication and signage
• Leather goods and textiles
• Paper products and packaging
• Glass etching and engraving

Limitations

• Cannot effectively mark bare metals (though can mark anodized or coated metals)
• Higher operating costs due to tube replacement
• Less energy efficient than fiber lasers
