About us

PHOTON ENERGY GmbH, an ISO 9001 / 13485 certified German company provides solutions for laser material processing and precision micro-machining. PHOTON ENERGY develops and manufactures pulsed and ultra short pulsed lasers for industrial and medical applications. The compact nano- and picosecond-DPSS-lasers are available as standalone and OEM versions. Besides laser sources PHOTON ENERGY offers also complete workstations and turnkey table top systems for marking and surface structuring applications, as well as for high precision micromachining.

Products and services

UDI regulations require lifelong markings on surgical instruments and in general on class 1-3 medical devices which are reused and reprocessed before each use. Conventional laser marking fails to deliver lifelong markings for this purpose on stainless steel.
PERMAblack, a contact-free marking technology by PHOTON ENERGY generates markings on stainless steel which are:

  • resistant against passivation, corrosion, autoclaving
  • deep black independent from viewing angle
  • pin sharp
  • high resolution
  • well readable throughout the entire expected product lifetime
  • non-cytotoxic
  • suitable also for implants since bulk material is not affected by heat

PERMAblack is also suitable for copper, brass, titanium alloys, aluminum.

PERMAblack is the perfect match for UDI.
PERMAblack is validated (FDA compliant).
PERMAblack is field proven for more than 5 years.


WORKSTATION is a universal laser processing cabinet for various marking and structuring applications up to 2.5D. It can be equipped with our ns-laser-sources LEO, AQUILA or FIBER or our ultrafast laser system CEPHEUS. It comes with a software-controlled Zaxis. Additional options include a rotation axis or an X-Y-table. The large semiautomatic door and the Z-axis vertical stroke of 300 mm enable markings of large and bulky objects.

The laser marking system MISTRAL was introduced in 1997 in Munich at the LASER World of Photonics trade fair. Because of its groundbreaking compact design it pioneered the era of compact laser marking systems.
Since that time we continuously adjusted and improved the technology used for the MISTRAL systems, today making it more precise than ever. Optional fittings include a camera system as well as a rotary axis.

A saturated black color of the metallic surface can be achieved by using the CEPHEUS ultrashort pulse laser with our proprietary PERMAblack marking process. The markings created with this laser have a deep black appearance that is independent of the viewing angle.
If corrosion-resistant parts are marked in black with the CEPHEUS laser, no subsequent passivation (protection against corrosion) of the marked surface is necessary, in contrast to marking with a nanosecond laser.
