About IPG Photonics
The record energy efficiency of IPG fiber lasers is enabling a transformation within the laser industry similar to the electric lighting industry. Over the years, advances in lighting and laser technology have improved the energy efficiency of these products and lowered the total cost of ownership.
Nd:YAG laser wall-plug efficiency is about 2%, which is equivalent to a traditional filament bulb. The majority of input energy is lost as heat. In a laser setting, this means that more electricity is needed to get required output power, necessitating powerful chillers to dissipate the significant heat which is effectively lost energy.
CO2 lasers are 3-5x more efficient than Nd:YAG lasers. More than 90% of input energy is lost to heat, much like a CFL light bulb. Significant cooling is still required for most industrial applications, further increasing energy usage.

IPG’s fiber lasers have efficiencies from 45–50+%, dramatically reducing the input power needed. In addition, fiber's high surface area to volume ratio combined with its efficiency significantly reduces heat output and the corresponding cooling cost of a chiller.
