Laser gas - Import export

CO2 laser marking systems are part of the gas laser group: the laser beam is generated in an enclosed laser tube which is filled with carbon dioxide. The REA JET CL is suitable for the marking of packaging, glass, wood, plastics, PVC, anodized aluminum, the color removal on surfaces as well as direct marking of foods. In the creation of texts, graphics and characters there is complete freedom of design. Applications — Marking of glass, wood, rubber, engraving and color change marking of plastics (automotive, medicine, consumer goods) — Coding of cardboard boxes and outer packaging (e.g. in the pharmaceutical, cosmetic and food sectors) — Coated substrates (e.g. anodized aluminum) — Direct marking of foodstuffs — Laser color change marking — Color mirror engraving

The Holo-Litho 405 is the ideal replacement for the vintage, power hungry Kr+ gas lasers (406.7 nm and 413.1 nm) commonly used in holographic and lithographic applications. While gas lasers require several kilowatts of electrical power and cumbersome water cooling, the “all‑semiconductor” Holo-Litho 405 draws < 0.08 kW and needs no water cooling to produce similar optical output power. This alone results in a significant reduction in cost of ownership. Furthermore the user also benefits from longer service intervals and lower refurbishment costs. Trained personnel can easily perform on-site replacements of the individual semiconductor field replaceable units, reducing down-time and increasing profitability.

The wavelength meters of the WS series accomplish wavelength measurements with highest accuracy. Both cw and pulsed lasers with narrow-band emission can be examined, monitored and even actively controlled. Various models of the WS series are available, covering UV to IR wavelength ranges (192 nm - 11 µm). Based on a rugged Fizeau interferometer setup without any moving components, the wavelength meters provide quasi unlimited lifetime.The spectrum analyzers LSA and HDSA allow for multi-line or broadband spectrum of light sources like cw and pulsed lasers, gas discharge lamps, super luminescence diodes, semiconductor laser diodes and LEDs.

Distributed feedback (DFB) laser diodes feature a grating structure within the semiconductor and thus operate in both longitudinal and transverse single mode. Tuning is achieved by modulating either the laser current or the chip temperature. Mode-hop free tuning is maintained over several hundred GHz. Applications include alkaline spectroscopy, laser cooling, gas detection and the generation of tunable cw terahertz radiation.

With the development of CHARM®, Open Grid Europe is providing an efficient leakage control method for natural gas pipeline networks and thus an alternative to the labour intensive practice of conducting on-site inspections of the pipelines with gas detection devices. CHARM® is a highly accurate infrared laser system integrated in a helicopter that is capable of precisely detecting even very low methane concentrations from the air. Even in the case of very complex pipeline topologies, the course of the pipeline can be detected consistently on a large scale during the flight by an automatic, highly precise scanning beam control system (autotracking), thus ensuring a reliable leak tightness inspection of the natural gas pipeline.
