Diamond C Series CO2 Lasers
Apr 2007
Coherent Inc.Request Info
SANTA CLARA, Calif., April 17, 2007 -- Diamond C, a new series of low-power, continuous-wave (CW) carbon-dioxide (CO2) lasers from Coherent Inc., now offers high reliability operation for OEM applications. The Diamond C series consists of sealed lasers with output powers of 30 W, 40 W, 55 W and 70 W at 10.6 µm.

According to the company, these lasers offer good amplitude stability (±5 percent for air-cooled models and ±3 percent for liquid-cooled units) and excellent output beam characteristics (M2 <1.2 for 30-W and 55-W systems, and M2 <1.3 for 40-W and 70-W models). For all models with improved cooling, the warranty is 24 months, and there are no gas refill requirements.

CoherentCO2Lasers.jpgBased on several key design innovations, the Diamond C series achieves superior performance compared to earlier, sealed CW CO2 lasers, Coherent said. These innovations include the use of new components and new resonator materials that optimize both laser efficiency and lifetime. In addition, laser cooling and temperature control have been improved to further benefit stability and lifetime.

Diamond C lasers are ideal for materials processing applications, such as marking and engraving, which generally require output powers less than 100 W. And because the radio-frequency power supply is inside the compact laser head, these lasers are easier for OEM system builders to integrate, Coherent said.

Typical marking applications include processing plastics, paper, medical packaging, PC boards and low-cost semiconductor products. Producing wood and plastic award plaques, keypads, rubber stamps, and stone and tile products are common engraving applications; these rugged lasers are also well suited for applications involving textiles and textile-related products, the manufacturer said.
