OXFORD, Mass. -- March 13, 2013

IPG Photonics Corporation (NASDAQ: IPGP) today announced the acquisition of
privately held Mountain View, California-based Mobius Photonics to accelerate
its entry into the UV laser market and deepen IPG’s development team. Mobius
provides high-power pulsed UV fiber lasers for micromachining, such as dicing
and scribing of wafers, and VIA drilling and solar hybrid panel processing.

“The acquisition of Mobius Photonics will augment our current development
efforts in UV fiber lasers to quickly penetrate the UV laser market, which we
believe could be a significant sales driver for IPG in the coming years.
Mobius has deep expertise in UV lasers, a strong patent portfolio and
proprietary techniques relating to UV lasers,” said Dr. Valentin Gapontsev,
IPG Photonics' Chief Executive Officer. “The market has been waiting for a
cost-effective, reliable and stable UV fiber laser. Now that we can combine
Mobius’ UV laser expertise experience with IPG’s low-cost, proprietary fiber,
pump diode and component technologies, we believe that we can effectively
build a presence in the fine processing market.”

“This combination will enable us to leverage IPG’s industry-leading fiber
laser technology to advance Mobius’ UV technology and provide our customers
with low-cost advanced UV fiber lasers,” said Dr. Robert Byer, Mobius'
Co-Founder and Chairman. “We are proud of the accomplishments of our talented
team and look forward to the many opportunities resulting from this
transaction.”

Kiyomi Monro, Mobius' CEO added, “I am pleased that the Mobius team will join
IPG, a company clearly committed to investing in technology and the people
behind it.”

In the acquisition, IPG acquired an exclusive license of U.S. Patent No.
5,745,284, an early and broad patent claiming pulsed fiber lasers with
frequency conversion into UV light, as well as other Mobius patents, licenses
and trade secrets.

The employees from Mobius will become part of the IPG Silicon Valley
Technology Center. Mobius had revenue from operations of approximately $1.4
million for 2012.
