The new Diamond E-400 from Coherent is a sealed, pulsed CO2 laser that offers an average power of 400W or a peak power greater than 1kW in a fully integrated, compact package. Incorporating the RF power supply within the laser head eliminates the RF umbilical in the Diamond E-400, increasing laser reliability and simplifying its integration into a workstation or robotic tool.
In addition to its reliability and long lifetime, the cost of ownership of the Diamond E-400 has been reduced, and improved serviceability has minimised downtime. Part of this is a full suite of on board diagnostics that lead to proactive maintenance in the future.
The pulsing characteristics derived from its slab discharge design enables the Diamond E-400 laser to reach peak powers in excess of 1kW, in contrast to CW modulated lasers. And the Diamond E-400 can be operated with pulse repetition rates up to 100kHz, with fast pulse rise and fall times. This combination of high peak power and fast rise and fall time times, together with power on demand and excellent beam quality (M2<1.2), makes the Diamond E-400 suitable for a wide range of materials processing applications. These include cutting metals, and drilling, scoring and scribing ceramics.
