STI Series RF-excited Ceramic CO2 Lasers

Most CO2 lasers offered today are based on the original R&D approach developed at several different aerospace companies in the 1970s. This traditional approach involves extruding or machining aluminum bodies to contain the optical and electrical components inside the laser gas envelope - the laser tube. These designs are convenient for R&D work, but not ideal for building lasers that are reliable, and have long lifetimes. The ceramic CO2 laser tube has a significant advantage.

The leading reliability issue with metal-tube lasers is that the metal is highly reactive with the gas mixture. Over time, as internal components wear, "scrub" each other's surfaces, fresh aluminum is exposed. Free oxygen in the laser's gas reacts with this raw metal (oxidation) changing the composition of the original gas mixture. In addition, many of these designs use O-ring seals that can allow air and moisture to enter the laser tube and further compromise the all-important gas mixture. These issues are eliminated with Ceramic CO2 laser tubes.

Ceramic CO2 laser tube technology solves these problems by moving all the reactive components to the outside of the laser tube leaving only pure clean Alumina (Al2O3) ceramic in contact with reactive gasses. Due to its chemical makeup, Alumina does not react with the gas. Alumina can also be fired at very high temperatures as part of the cleaning process. This further assures there are no organic contaminants from laser tube manufacturing, that remains inside the laser tube to react with the gas.

The ceramic CO2 laser tube is also the optical backbone that holds the resonator optics. The CTE (coefficient of thermal expansion) of alumina is 1/3 the CTE of aluminum. Since laser tube thermal variations have a direct impact on laser stability, Our Ceramic CO2 laser tube has significantly better stability performance when compared with metal-based CO2 lasers. Ceramic CO2 laser tubes also enables gas mixtures of comparatively high pressure to be used. Ceramic CO2 laser tubes allow for high pressure gas mixes and provide for faster rise and fall speed as well as much better power stability.

Infinity 1625 Ceramic CO2 Laser, The lightest, most compact 250 Watt CO2 laser source

Our model 1625 is a 250 Watt CO2 laser tube and is based on our proven Ceramic Core Technology. Model 1625 is the smallest RF-driven, sealed CO2 laser in the world.

RF Driven CO2 lasers are typically designed to operate in a pulsed mode, at a specified Peak-Power. The pulses can vary in duration from near zero to continuous-wave (CW) - the laser is on continuously. Further, at the time of shipping, a laser could produce a significantly more peak-power than specified.

This additional, or reserve power is common in CO2 lasers, and is intended to further the specified lifetime of a laser that is known to have power degradation over time; the laser will stay within specification longer.

Z30/Z40 Series RF-excited Ceramic CO2 Lasers, The smallest RF driven 30 and 40 Watt laser

Our model Z30/Z40 is a 30/40 Watt CO2 laser tube and is based on Our proven Ceramic Core Technology. One of the primary differences and technological advancements that is incorporated in this design is the resonator. The Z30’s/Z40’s resonator is a Z-folded (2-fold) unstable resonator. This allows for a smaller package design when compared with other 30/40 Watt laser tubes and is the shortest (folded) resonator in the 30 – 50 watt CO2 laser class, but has a remarkably long (unfolded) resonator length. This provides superior power and beam diameter stability. Early test have shown the from-cold power stability in the ±2% range.

ULR Series RF-excited CO2 10-500W Lasers

The ULR series of CO2 lasers for OEM use are based on a sealed, RF pumped, slab design that produces a high-quality beam. These lasers can be operated in CW mode or modulated to control average power. Modulation is accomplished by varying the pulse width of the input signal.

In the 10 W to 500 W lasers, RF electrodes are spaced apart to allow the laser beam to form without influence of the electrodes, delivery excellent near- and far-field quality with minimal wave-guide effects. The folded resonator design allows generation of power in a compact package. Our lasers require no consumables and deliver a very long lifetime.

Advantages

When you purchase an OEM laser you are not only buying a laser source, but a partnership. That partnership means you receive direct access to world-wide technical support and the shortest service turnaround times, access to the most advanced Applications Laboratory and the most robust and reliable lasers on the market for as long as you own and use the product.

Beam Output Configuration:

With the 90 degree output the beam goes through the base plate. We cut a hole in the bottom and mount it to the face of the laser, turn it 90 degree down through the hole. We can not offer it in any other direction but through the bottom of the base plate. To offer this option on OEM lasers the beam output number is (#3) for 90 degree without pointer, (#4) for the 90 degree with pointer. This option is not offered on 10W Integrated air cooled due to the small base plate and no room to mount the out put.
