Advanced Laser Diode Systems A.L.S. GmbH was founded in 2002 to produce and develop efficient pulsed laser diode systems, related components and accessories for the application in industry and science.

Since 2008 A.L.S. GmbH is a subsidiary of the Switzerland based company Onefive GmbH. Scientists, engineers and technical staff at A.L.S. and Onefive have a longstanding experience in the field of this modern laser technology product line and contribute to the success of the company. Advanced Laser Diode Systems A.L.S. GmbH became already a leading manufacturer of lasers, laser systems and laser components.
The main product line of the company is based on ultra-fast picosecond laser diode systems.

In general A.L.S. provides turn-key systems which can be used just as a tool. But A.L.S. is also ready to produce customized solutions for special applications and OEM components.

In Germany and countries, where A.L.S. GmbH does not have representatives, the products are sold directly to the end customers. In many countries, however, A.L.S. GmbH has representatives. Please check our distributor links.

Advanced Laser Diode Systems A.L.S. GmbH is located in Germany in the Photonic Center in Berlin-Adlershof. All products are exclusively made in Germany. Most engineering of our products is done in-house. However, to accelerate the development we use also successful co-operations with research institutes and universities.

The facilities are located in the South-East of Berlin near the Airport "Berlin Schoenefeld" (SFX) in the "WISTA" area in Berlin-Adlershof. This so called "WISTA" area has a long High-Tech tradition and is the main development area in Berlin for optical technologies as well as for environmental protection and telecommunication. Many High-Tech companies, research institutes and the natural science departments of the Humboldt University of Berlin are located here or will move to the WISTA area in near future. The efforts of the Senate of Berlin, supported by the European Community, will lead to a successful infrastructure.
