Trumpf TruDisk disk lasers benefit from intelligent energy management technology
1 min read
Trumpf calculates that its intelligent energy management technology now provided at the 6 kW and 2 kW power levels of its TruDisk disk lasers add another 25% to the existing energy consumption savings they offer. The system also senses when the laser has stood idle for a while and puts it in standby mode and optimises grid voltage quality.
Trumpf TruDisk disk lasers are more compact than their forerunners and use highly efficient diodes to pump the laser. Combined with an optimised resonator design – resulting in efficiency gains of up to 70% – the system is also capable of achieving overall beam source efficiencies of well over 30%. The company therefore puts the power consumption at 90% of that of flash lamp pumped lasers.
An efficient heat exchanger and integrated cooling water management also contribute to the green credentials of this design.
Around 10% of applied energy is typically lost en route from resonator to the workpiece as the laser beam passes through a series of components, such as the fibre optic cable, control system and focusing optics. Trumpf points out that calculations that only look at beam source power consumption often ignore these losses. The power figures quoted are for power at the workpiece and factor in transit losses.
