Coherent Diamond C/C+

Reliable and cost-effective Coherent Diamond C and C+ CO₂ lasers with output power from 20 to 70 W and a service life of over 50,000 hours. Ideal for laser marking and cutting.

The Diamond C and C+ laser sources from the Coherent C-Series are compact and cost-effective CO₂ lasers with average output power from 20 to 70 W. They are specifically designed for industrial laser marking and cutting systems. Thanks to their sealed waveguide, fully integrated RF power supply, and modular platform, they offer unmatched reliability, long operating lifetime, and stable optical performance across a wide range of applications.

Extreme Lifetime

The sealed waveguide architecture ensures a production-proven lifetime exceeding 50,000 operating hours.

3 Wavelengths (9.3 µm / 10.2 µm / 10.6 µm)

They ensure perfect adaptation to the absorption properties of the processed material for clean and fast cutting.

IP65 Protection (for the C+ Series)

The Diamond C+ version offers advanced protection against dust and moisture ingress (IP65), making it an ideal choice for demanding operating environments.

Product description

Diamond C / C+ lasers belong to the long-proven Coherent C-Series family. They combine extremely compact dimensions, cost-efficient operation, and high reliability. Innovative sealed waveguide technology together with an integrated RF power supply ensures highly stable optical performance. The total service life of the device commonly exceeds 50,000 operating hours, which represents a top-tier standard in industrial applications and radically reduces machine ownership and maintenance costs.

The modular platform design allows production in various configurations. Optimization of the operating wavelength in the range of 9.3 to 10.6 µm ensures that the laser can be precisely adapted to specific materials. High beam quality and power stability contribute to consistent and perfectly sharp results in marking, engraving, and cutting.

Thanks to their exceptionally small footprint, unified communication interface across the entire power range, and the option to choose between air and water cooling, these lasers are a favorite among OEM machine manufacturers. For installations in dusty or otherwise contaminated industrial environments, a special Diamond C+ variant is available, featuring a high IP65 protection rating against the ingress of liquids and contaminants.
