EKSPLA’s Dry Cooling Technology Featured on the Cover of Photonics Spectra

November 6, 2025

Laser technologies often move from research laboratories to the battlefield — but this time, a cooling innovation made the reverse journey.

Dry cooling technology developed by EKSPLA engineers is featured as the cover story in the latest issue of Photonics Spectra, the industry’s leading magazine with the largest worldwide circulation in lasers, optics, and photonics.

As lasers continue to advance across industrial, scientific, medical, and defense sectors, the importance of efficient and reliable thermal management grows. Every laser system requires a cooling solution tailored to its power level, environmental conditions, and performance requirements. Poor thermal control can cause wavelength drift, reduce efficiency, and shorten a system’s lifetime — making cooling design an important part of overall laser reliability.

The Photonics Spectra article examines how EKSPLA’s direct refrigerant cooling (DRC) technology redefines laser thermal management, offering higher efficiency and long-term stability compared with traditional air- or water-based systems. Among the key topics explored are:

  • The main cooling approaches and their advantages
  • A comparison of dry cooling with conventional chiller and air systems
  • The origin and principles of direct refrigerant cooling
  • Insights from real-world performance data

The FemtoLux series of industrial femtosecond lasers showcases how this technology closes an important innovation loop. A cooling solution once designed for demanding military environments has been refined and adapted for high-precision industrial manufacturing — where uptime, energy efficiency, and cost control are equally mission-critical.

From the field to the factory, direct refrigerant cooling is proving to be a reliable, efficient, and forward-looking solution for the next generation of ultrafast lasers.
