Its products are sold globally and primarily used for materials processing, advanced technologies, telecommunications, and medical applications.

This created a high power, infrared laser, with single mode beam quality.

In 2018, these amplifiers are used in telecommunications and Internet networks to transmit data over optical fiber and free space.

[17][18] In order to introduce the technology to the market, Italtel convinced Gapontsev to transfer component production to Italy.

In 1994, Daimler Benz Aerospace (DBA), a German company, hired IPG to create a laser-based obstacle warning system for a helicopter.

[19] IPG continued developing new products and selling them to customers in Japan, the United States, and Europe.

During this time, IPG started developing its multi-kilowatt diode-pumped fiber lasers.

[22] By the end of 2000, capital spending by telecommunications providers was reduced and IPG revenue from communications applications declined.

[24] The company continued to expand, opening offices near Detroit, Michigan in 2006, Beijing, China in 2007, and its Silicon Valley Technology Center in San Jose, California in 2010.

[4] IPG announced the release of the LightWELD 1500, a handheld laser welding system, late in 2020.

In late 2017, IPG announced the acquisition of Laser Depth Dynamics, a provider of an optical coherence tomography-based in-process quality monitoring and control solutions for laser-based welding applications.
