These RF-excited CO2 lasers are made in USA and are widely used in the processing of non-metals such as plastic organic materials BBS etc. CO2 laser tube is based on Our proven Ceramic Core Technology.

Product Introduction

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 Series RF-excited Lasers

The Infinity Series includes RF excited, 40, 60, 80, 100, and 120 Watt CO2 lasers. For customer convenience, all models have identical form and fit with internal RF-drive electronics. If a different power laser is required, only the DC power supply will require changing. 40, 60, 80, 80, 100, and 120 Watt CO2 lasers are offered in three different cooling configurations. The Air-Cooled configuration allows for the customer to supply the necessary cooling air for the laser. The Fan-Cooled configuration comes fitted with cooling fans. The water cooled version is supplied with an input and output port to connect a chilled water source. All configurations of 40, 60, 80, 100, and 120 Watt lasers are built around our patented ceramic core technology that provides superior lifetime, reliability, and stability.

Model 1625The 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 LasersThe 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.

**  Output power is guaranteed to exceed this level for a period of 15 months from the date of purchase, regardless of use.

***  At temperatures below 50ºF[10℃] operation may be intermittent and there is a potential for damage to the power supply optics.

There are 3 types of configurations of each  laser: OEM BASIC, OEM INTEGRATED and Class IV.

OEM BASIC: This configuration is a basic laser tube and RF power supply. There is no cover, no fans. This is for the OEM to integrate into their equipment and provide the proper cooling and protection. Air cooled or water cooled must be specified at time of ordering.

OEM INTEGRATED: This is the configuration that we have been offering for a number of years. The laser tube and RF power supply are covered with a shroud and have the fans included.

Class IV: This configuration has a cover, manual shutter, keyed lockout switch and fans or water connections, depending on type. Air cooled or water cooled must be specified at the time of ordering.

For used Universal lasers, we provide fully-refurbishing services at very low prices. The refurbishing includes replacing optics, RF power supply and refilling gas. All the jobs will be finished within 7 days.

Main Difference between UL Series and ULR Series Lasers

The bottom and connector are swallow-tailed and 12PIN respectively but the bottom and connector are flat and 15PIN respectively. There is no difference on performance.

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.
