Laser Parts & Components
Replacement CO₂ laser tubes, excimer laser components, and laser power supplies for industrial manufacturing, medical applications, and semiconductor lithography. Global supply from PartnerTubes.
CO₂ Laser Tubes
CO₂ laser tubes are gas-discharge devices that produce laser light at 10.6 μm (far infrared). They are the most widely used industrial laser type due to their high efficiency (10–30%), high power scalability, and ability to process almost any non-metallic material. PartnerTubes supplies both sealed (RF-excited) and flowing-gas (DC-excited) CO₂ laser tube types:
- RF-excited sealed CO₂ tubes: 10 W – 600 W output; compact design; used in laser engravers, markers, and medical devices
- DC-excited sealed CO₂ tubes: 20 W – 300 W; economical; widely used in cutting and engraving machines
- Flowing-gas CO₂ tubes: 1 kW – 20 kW; for heavy industrial cutting and welding
Excimer Laser Tubes & Components
Excimer lasers produce high-energy ultraviolet (UV) pulses at wavelengths between 126 nm and 351 nm. They use rare gas-halide mixtures (argon fluoride, krypton fluoride, xenon chloride, xenon fluoride) to form excited-state molecules (excimers) that emit UV light. PartnerTubes supplies:
- ArF (193 nm) laser chambers and components — semiconductor lithography
- KrF (248 nm) laser modules — lithography, material processing
- XeCl (308 nm) modules — medical dermatology (psoriasis, vitiligo treatment)
- XeF (351 nm) excimer components — scientific and research applications
Ion Laser Tubes
Argon and krypton ion laser tubes for spectroscopy, holography, confocal microscopy, flow cytometry, and scientific research. These are low-production, specialist devices for laboratory and research equipment maintenance.
Laser Power Supplies & Accessories
Complete laser power supply units, high-voltage drivers, RF generators for RF-excited CO₂ lasers, cooling system components, and optical components (mirrors, lenses, output couplers) for laser system maintenance.

Frequently Asked Questions
How do I select the right replacement CO₂ laser tube?
Key parameters are: rated power (watts), bore diameter (affects beam quality M²), tube length (determines focal range and cavity length), excitation type (RF or DC), and operating voltage. Most laser machines specify the tube by power (e.g., "60W tube") and length. PartnerTubes can cross-reference by machine brand/model or tube dimensions. We recommend specifying original power and length for a like-for-like replacement.
What is the difference between RF-excited and DC-excited CO₂ laser tubes?
RF-excited CO₂ tubes use high-frequency RF power (typically 40–81 MHz) to excite the gas. They offer: longer lifetime (20,000–50,000 hrs), better beam quality, faster modulation speed, and no electrode erosion. DC-excited tubes use direct current for excitation. They are lower cost but have shorter lifetimes (2,000–8,000 hrs) due to electrode sputtering. RF tubes are preferred for precision and high-duty-cycle applications; DC tubes are common in economy cutting and engraving machines.
Do you supply parts for Coherent, Synrad, or Trumpf CO₂ lasers?
Yes. PartnerTubes sources replacement tubes and components compatible with CO₂ laser systems from Coherent (formerly TRUMPF CO₂ division), Synrad (now Novanta), Epilog, Universal Laser Systems, and other major manufacturers. Contact us with the laser model number or tube part number for availability.
Can you provide excimer laser components for semiconductor equipment?
Yes. We source excimer laser components for lithography and photolithography systems. This includes ArF and KrF excimer modules, laser chamber components, thyratrons for laser pulsers, and associated high-voltage electronics. Contact our technical team with your system platform (Cymer, Gigaphoton, Lambda Physik/Coherent) and required specifications.
