Rofin Sinar CO2 Laser Resonators

SM-series

The ROFIN-SINAR CO2-Laser in the SM-range have been established in a wide variety of industrial applications for many years. The SM-lasers are a universal tool, used mostly in cutting systems as well as a wide range of welding applications.

The SM-range has set the standards for durability, outstanding beam quality and performance stability.

Four Invar tubes are used to hold the two endplates at precise distance apart. This forms a rigid assembly onto which all optical components are mounted. The discharge tubes are supported on a polymer concrete composite section, thereby ensuring adjustment-free optical alignment with high mechanical and thermal stability even in case of exchanging components in the discharge region.

RF-series

Rofin Sinar CO2 Lasers RofinSinar Laser - Franek Laser - SLAB-Series

The ROFIN RF is the first high-powered CO₂ laser with a wear-free outcoupling window made of synthetic diamond. This makes it possible to keep beam parameters constant across the entire control range, and increases up-time.

Its excellent beam quality of M˛ < 2.5 (TEM_01*) makes the ROFIN RF laser suitable for cutting thick sheet metal, as well as thin sheet metal and for welding with minimal heat affected zones.

The laser is a compact unit with all supply and control systems integrated in it, which minimizes the footprint, and means extremely short startup times.

The maintenance-free, free-running, high-power RF generator is coupled directly to the resonator without cables. The use of only one RF transmission tube gives the laser a long lifetime.

Operation with premix gas, as opposed to separate gases, means that an internal gas mixer can be dispensed with. This reduces the external laser gas installations to one third.

HF-series

With its Cross-Flow HF-series, ROFIN-SINAR replaces the established DC-excited predecessor. The new HF-CO2 lasers feature advantages such as low running costs, industrial design and a beam profile ideal suited to a wide range of welding and surface-treatment applications. The most compact multi-kW industrial laser available on the market, the HF-Laser requires a minimum of space and can be easily integrated into automated production systems.

1. Laserbeam 2. Tangential blower 3. Gas flow direction 4. Heat exchanger 5. Rear mirror w/real time power monitor	6. Fold mirror 7. HF-electrodes 8. Output mirror 9. Output window
The resonator features a multi-pass optical path with mirrors mounted on a temperature stabilized graphite composite tube resonator structure to ensure optical stability. Laser gas is circulated into the discharge region via a tangential blower and is cooled by a heat exchanger. Gas flow orientation, High Frequency (HF) discharge and optical path are at right angles to one another, resulting in a compact design capable of delivering a multi-kilowatt laser beam.

DC-series "SLAB"

The diffusion-cooled CO2-Slab-Laser from ROFIN-SINAR marks the advent of a new era in industrial laser technology whether for cutting, welding or surface treatment. The revolutionary design of the Slab-Lasers offers such decisive advantages as extremely compact design and the elimination of an external gas supply. Gas consumption is negligible, the gas cylinder integrated into the laser head lasts for approximately 12 months continuous use. Further features include an extremely high beam quality and a significant reduction in service requirements.

2. Beam shaping unit
3. Output mirror
4. Cooling water
5. RF excitation

6. Cooling water
7. Rear mirror
8. RF excited discharge
9. Waveguiding electrodes

The optical resonator is formed by the front and rear mirrors and two parallel RF-electrodes. Excitation of the laser gas takes place in the RF field between the water-cooled electrodes. The heat generated in the gas is dissipated by the water-cooled electrodes (diffusion cooled). Thus, the conventional gas circulation systems involving roots blowers or turbines are not required. A beam shaping module is integrated into the laser head and produces a high quality round symmetrical beam. The resonator design produces a 45° linearly polarized beam.

SR-series

Wherever a high output is required the ROFIN-SINAR CO2-Lasers from the SR range are an ideal choice. Welding of thick sheet steel, cladding or heat treatment of large surfaces are applications idealy suited for these lasers. Thanks to its high output power and beam quality the SR range is used for welding purposes in the fields of shipbuilding and pipeline production, to name just two. A large number of well known research institutes use these lasers for process development work.

The SR series of high power CO2 lasers are based on the proven fast axial flow principle with the RF power supply module integrated into the laser head unit. Turbo radial blowers are used to transport the laser gas through the resonator. A patented corner cube reflector arrangement of the fold mirrors guarantees highest beam stability utilizing only one fold.
