TruCoax light and compact

Diffusion-cooled laser for thin sheet metal

Trumpf's TruCoax series of CO2 lasers offer minimal gas consumption and high beam quality. The TCF 1, successfully launched in 2005, is now called the TruCoax 2000. There is also a TruCoax 1000. The coaxial arrangement of the electrodes in the diffusion-cooled TruCoax lasers deliver high beam qualities while at the same time remain sensitive to the alignment needs of the system at the same time. The beam qualities of K = 0.9 make the laser ideal for cutting and welding of smaller and medium sheet thicknesses. An integrated beam-forming telescope ensures a high beam symmetry even at large distances.

The principle of free-space beam propagation in the resonator, in conjunction with the coaxial arrangement of cooling electrodes, results in a particularly compact and robust construction. The resonator combines all functions in one structure. The electrode tubes act as the bearing structure of the laser and the assembly platform of the beam-forming telescope.. Additionally, the outer electrode also serves as the high-frequency shielding.

The vacuum system is limited to the annular gap between the electrodes. Gas consumption is therefore considerably lower than for comparable beam sources. The gas supply is integrated into the compact laser head and ensures continuous operation for more than a year. A semi-automatic gas exchange takes place every 72 operating hours only (near sealed-off operation).

The compact, light weight design of the TruCoax laser makes it easy to integrate them into robot systems or any other production system. With very low power consumption in stand-by mode, the TruCoax lasers use less energy in applications requiring low beam-on times.
