From Invention to Innovation

In 1990, lifelong laser pioneer Dr. Valentin Gapontsev proposed the world's first high-power fiber laser design which used laser diodes to pump along the length of a doped optical fiber. Shortly after, Dr. Gapontsev developed the first five watt fiber laser and founded IPG Photonics. 

Today, IPG has developed lasers with powers in excess of 100 kilowatts and offers the widest range of laser capabilities available. With a dedication to total control over product quality, we design and manufacture all key laser components to ensure IPG laser technology never compromises on performance.

IPG innovation continues to push the industry forward, offering fiber laser solutions with the reliability, energy efficiency, and capabilities necessary to support the most advanced applications around the world.

Innovation Powered by Optimization

The world's most efficient and reliable lasers require the highest performance building blocks. From crystal growth to diode production and from high-efficiency power supplies to innovative pumping architectures, every IPG laser is powered by the highest performance components manufactured and rigorously tested at IPG facilities.

The same commitment to quality and innovative capabilities extends to every IPG laser solution including beam delivery, real-time process monitoring, and laser systems from handheld to fully automated production lines.

IPG Innovation Drives Sustainability

The evolution of laser sources is similar to the evolution of lighting sources. Compared to all other lasers, including alternative fiber lasers, IPG fiber lasers offer the highest energy efficiency. Renowned for producing the most energy-efficient lasers globally, we empower our customers to reduce costs while contributing to energy savings and reductions in CO2 emissions. Manufacturers continue to choose IPG fiber lasers to maximize their productivity, minimize their bottom line, and replace inefficient alternative technologies with truly sustainable laser solutions.

Nd:YAG Lasers are only 2% efficient.

Nd:YAG Lasers

2% Efficient


The efficiency of lamp-pumped Nd:YAG lasers is approximately 2%, comparable to a traditional filament bulb. The remaining 98% of input energy is lost as heat. Excess electricity is needed to obtain the targeted optical output and considerable power must be dedicated to the dissipation of an enormous amount of waste heat.

Energy efficiency for CO2 lasers is around 7 to 8%.

CO2 Lasers

7 to 8% Efficient


Although gas CO2 lasers are 3 to 5 times more efficient than lamp-pumped Nd:YAG lasers, over 90% of the input energy is lost as heat. This efficiency is similar to that of a fluorescent lamp. Significant additional energy is required to achieve desired laser optical power and to power chillers to dissipate heat loss.

IPG fiber lasers boast energy efficiencies ranging from 40 to 57%.

IPG Fiber Lasers

40 to 57% Efficient


IPG fiber laser efficiencies are comparable to modern diode light sources. Highly efficient diode pumping, proprietary laser architecture, and high surface-to-volume ratio of the fiber all combine to dramatically reduce electrical power consumption to provide more cost-effective and sustainable laser solutions.
