If your laser builder has stopped answering the phone, discontinued your parts, or quoted you a six-month lead time on a flashlamp, you are not stuck. TJS stocks and rebuilds components for solid state, CO2, fiber, and diode systems from more than 25 manufacturers, including Coherent, Trumpf, Rofin, Spectra Physics, Lumonics, and JK Lasers. If you cannot locate the component you need, TJS will help you find it.
Quick Answer
Yes. TJS stocks, rebuilds, repairs, and supports parts for legacy solid state, CO2, fiber, and diode laser systems from more than 25 manufacturers. If the OEM has discontinued support, TJS can often locate the component, rebuild the assembly, or help determine when replacing the laser is the smarter move.
Best for hard-to-find parts, obsolete systems, emergency downtime, and repair-vs-replace decisions.
Most laser owners learn this the hard way. A system goes down, the original manufacturer has moved on to a newer model, and the part that used to ship in a week now doesn't exist. That is the gap TJS has filled since 1980. Below is what that support actually covers, why a third-party shop often knows your laser better than the company that built it, and what to do when a system finally reaches the point where repair stops making financial sense.
TJS carries the full range of consumables and replacement components needed to keep solid state, CO2, fiber, and diode lasers running. That inventory includes OEM krypton and xenon arc lamps and flashlamps, mirrors, lenses, optics, fiber optic delivery systems, water filters, pumps, flow tubes, dust windows, laser crystals, q-switches, flashlamp power supplies, RF drivers, galvanometer motors and mirrors, and complete laser head assemblies.
The list runs deeper than the parts that wear out on a schedule. TJS stocks capacitors, chokes, circuit breakers, dichroic mirrors, diodes, EMI line filters, krytron tubes, Nd:YAG rod assemblies, PC boards, SCRs, transformers, water pump seal kits, and the smaller items that strand a laser when they fail, like O-ring kits and lamp clips. When a board or a pump chamber can be rebuilt rather than replaced, TJS handles that in-house too.
Diagnostics matter as much as the parts. TJS supplies alignment and measurement tools, including infrared viewing cards, autocollimators, laser power meters, and alignment lasers, so a technician can confirm the real problem before swapping hardware. That same depth of parts and diagnostic knowledge is what TJS engineers draw on when they build and support the Endeavor fiber laser line.
Yes, and in many cases a specialist service shop has more practical knowledge of your laser than the company that originally sold it. TJS keeps OEM-level parts for legacy builders including Lumonics, Control Laser, Lasag, U.S. Laser, General Scanning, Carl Baasel, and more than twenty others, many of which have been acquired, renamed, or have dropped support for older platforms.
When a manufacturer discontinues a product line, the institutional knowledge usually leaves with it. The engineers who designed the system move on. The spare parts inventory gets liquidated. The owner is left with a working machine and nobody to call. TJS built its business in that exact space. Decades of servicing and repairing other companies' lasers means the team has seen the failure modes, sourced the obsolete components, and worked out the fixes that the original documentation never covered.
This is also where the Endeavor story begins. TJS designed the Endeavor RETRO around 40-plus years of repairing and retrofitting laser systems, drawing directly on the knowledge of what causes lasers to fail and how to build them so they don't.
Most industrial lasers can run for years past their original service life as long as consumables stay available and a qualified shop can rebuild the failure points. The deciding factor is rarely the laser cavity itself. It is the cost and availability of the parts that wear out around it, and the downtime you absorb each time one fails.
There is a tipping point. When a flashlamp-pumped system needs a new lamp every few hundred hours, when a chiller leak takes out a pump chamber, when you are tracking down obsolete boards through gray-market sellers, the math shifts. The repair bills are real, but the bigger number is the production you lose every time the machine sits idle waiting on a part. In the tool and die sector, TJS has seen jobs that once took more than three hours drop to under three minutes after a fiber laser replaced an older Nd:YAG flashlamp-pumped system. That kind of cycle-time difference often outweighs the cost of continuing to nurse a legacy machine.
TJS will keep your existing laser running for as long as that makes sense for your operation. When it stops making sense, the same team can tell you honestly, because they have no reason to sell you a repair you don't need.
When repair is no longer the smart move, TJS replaces the laser without forcing you to scrap your workstation or automation. The Endeavor RETRO is built as a replacement for any existing flashlamp, diode pump, CO2, or other laser system, swapping in the laser and controls while you keep your existing workstation and most of your automation.
The RETRO was designed for this exact situation. It has a small footprint and a flexible interface, so it mounts on existing automation, conveyors, and other part-processing infrastructure. RETRO systems are air-cooled and run on 120VAC, which makes integration straightforward and keeps operating cost down compared with systems that demand 230VAC three-phase power. You are replacing the part that failed, not rebuilding your entire production cell.
For owners who want a complete turnkey system rather than a drop-in, the Endeavor J-Series is a Class 1 fully enclosed fiber laser workstation. It comes in 20W, 30W, 50W, 70W, 100W, and 200W air-cooled MOPA configurations, with both infrared (1.064nm) and visible (.532nm) options available depending on the material and application.
TJS backs its fiber lasers with a 3-year warranty because the Endeavor line has a documented field-failure record of zero. Since the Endeavor MOPA fiber laser line was introduced in 2014, TJS reports no field failures to date, a 100 percent success rate. A company that spends its days repairing other manufacturers' failures has a clear view of what a reliable system needs to be.
The warranty length is a direct product of how the system was engineered. The Endeavor uses a modular design for straightforward maintenance, and the fiber lasers are essentially maintenance-free, with no spare parts required and simplified air-cooled, 120VAC power. Fewer wear items and fewer failure points mean the manufacturer can stand behind the product for longer. Every Endeavor system is designed, manufactured, and assembled in the United States, and the same U.S. facility serves as the primary technical support hub, so customers reach the engineers who actually built the system.
That is the full circle of what TJS does. The company keeps your current laser of any brand alive as long as it makes sense, supplies the parts and diagnostics to do it, and when the day comes that the old system has given everything it has, there is a fiber laser ready to take its place that, so far, has never failed in the field.
If you are hunting for a hard-to-find component or weighing whether to repair or replace, the TJS service team can help you locate the part or work through the decision.
