Spectra-Physics Stahnsdorf
Rugged, Ultra-compact Industrial Lasers

Spectra-Physics® is a leading global supplier of laser systems. At our facility near Berlin, Germany, we develop and manufacture the most compact, reliable, and durable nanosecond OEM lasers serving many high-volume applications. These lasers offer infrared, green, and ultraviolet light with unmatched performance parameters.


Deep Experience and Expertise

Founded in 1992 as a spin-out from the Technical University in Berlin, Laser Analytical Systems (LAS) was acquired by Spectra-Physics in September 2000. In the late 1990s, LAS introduced several leading-edge laser products that generated deep UV at 244 and 266 nm, using patented enhancement cavity designs targeted for the fast-growing telecom market and high-end research applications. After the telecom market bubble, the R&D efforts were directed toward developing cost-efficient nanosecond pulsed industrial-grade OEM lasers. Today, we manufacture the Explorer® laser series, serving OEM customers in diverse volume applications. The Explorer product family uses an internally developed, highly automated laser resonator alignment technology. Close collaboration with Newport™ colleagues enabled us to take advantage of expertise and know-how in motion control when developing this highly advanced and unique pick-and-place technology to build lasers in high volumes.

What We Stand For

We deliver ultra-compact, highly reliable, and durable lasers, enabling our customers to push the envelope by developing smaller, lighter, yet more powerful instruments in the smallest footprint possible. With a worldwide installed base of several thousand Explorer lasers, our customer base ranges from small start-ups to large global corporations. Customer satisfaction is our #1 priority. We listen to customer needs and transform them into laser requirements. The high degree of automation in our manufacturing enables customized, tailored specification reports. Each Explorer laser undergoes extensive test procedures and is inspected to rigorous standards, including thermal cycling and shock testing exceeding 200 g’s of acceleration. Out-of-the-box or infant failures are essentially non-existent.

The worldwide presence of Spectra-Physics, an MKS brand, features numerous production facilities around the world and an international network of direct sales and service hubs. This extensive, global network provides superior service and dependable support local to our customers.

Short Pulse Nanosecond Lasers – Ultra-compact Industrial Lasers

The Explorer® series lasers are manufactured in clean rooms of ISO Class 5 Standards and better. From start to finish, the lasers are built in highly controlled manufacturing areas, applying strict quality control standards and requirements. Our implemented Data Management Tools ensure 100% component traceability for each laser we build. In addition, each laser undergoes a 100% inspection test and is exposed to thermal cycling and bare product shock testing exceeding 200 g’s of acceleration as part of the manufacturing cycle. These rigorous tests eliminate out-of-the-box failures and demonstrate the ruggedness and durability of the Explorer series lasers. Lean manufacturing and six-sigma methods are applied to drive continuous product improvements in our quest to develop the most reliable industrial lasers. Explorer customers benefit from the following features:

  • One footprint offering green (GR) and ultraviolet (UV) models
