End of manufacturer support removes the factory exchange route. It does not remove the instrument from your optical table, and it does not remove the possibility of repair. This page sets out what is still achievable, and where the real limits are.
Scientific laser companies consolidate. A platform designed by a small specialist firm gets acquired, the acquirer is acquired in turn, product lines are rationalized, and a system that was current a few years ago appears on an application page marked obsolete. Nothing has changed physically. The instrument on the bench is the same instrument.
What changes is everything around it:
The laboratory is left with a capital instrument, an experiment that depends on it, and no route. That is the situation this page addresses.
Obsolescence is a commercial status, not a verdict on the hardware. The subsystems that fail on these platforms are ones we work on at component level regardless of what the catalog says.
Laser diode drivers, high-speed seed drivers, pump-current controllers, protection circuits, power supplies and rails. Built from components that are still identifiable and in most cases still obtainable or substitutable.
TEC modules and drivers, temperature sensors, crystal ovens, fans, chillers and thermal wiring. Among the most common failure areas and among the most repairable.
Monitor photodiodes, conditioning circuits, converter stages and control loops. A system reporting a false value is a repairable fault and is frequently mistaken for a dead laser.
Connectors, end faces, splices, pump combiners, isolators and mode-field adaptors. Damage here removes the output with no electrical trace, and much of it is addressable.
Interlock chains, shutters, trigger and synchronization inputs, serial interfaces and communication hardware. Repairable, and where the original interface is genuinely gone, replaceable with an engineered equivalent.
Non-standard cables and connectors are a frequent single point of failure on orphaned systems and are among the most straightforward items to rebuild once the pinout has been established.
Crystal ovens, their control, separation optics and mounts. Crystal replacement itself is case by case, as set out on the SHG page.
A documented failure analysis, with measurements, is a deliverable in its own right. It is frequently what a replacement purchase request has to be justified with, and it is worth more than a verbal opinion.
It is more useful to be specific about what ends a repair than to imply that nothing does.
Where the failed item is a purpose-built assembly manufactured only by the original company, with no equivalent available and no realistic path to engineering one within the value of the instrument, the repair ends. We report that in writing with the evidence.
Some modules contain alignment that is established at manufacture and destroyed by opening the housing. Where there is no realignment path without factory tooling and data, opening it converts a faulty instrument into a scrap instrument. We do not do that without telling you first and getting a decision.
Certain optical damage, particularly in fiber systems that have run through a high-power event, is not repairable at any sensible cost. We identify it rather than replacing components around it and hoping.
We do not perform manufacturer-equivalent calibration, and we do not certify a system to original published specifications where the original acceptance data and the corresponding standards are not available. A certificate written against numbers we cannot verify would be worthless to your laboratory and to anyone auditing it.
Some repairs are technically possible and financially absurd. We quote them honestly and say so, and we do not treat a laboratory's willingness to pay as a substitute for advising against it.
When an original part no longer exists, there are three routes, and the right one depends on the instrument and its remaining service life.
Any substitution or engineered replacement is recorded in the service report as a deviation from original design, with what was fitted, why, and what behavioral differences to expect. That record belongs in your instrument file. A laboratory that does not know its laser has been modified will eventually be misled by its own documentation.
On discontinued systems, the customer's own paperwork is frequently the only surviving record of the configuration. Manuals, configuration sheets, acceptance data, purchase specifications and previous service reports are worth sending even when they look incomplete or irrelevant, because on an orphaned platform an incomplete original document outranks a complete assumption.
Where no documentation exists at all, the configuration is established on the bench by measurement and inspection, and that work is part of the evaluation rather than something that happens before it. We tell you when that is the case, because it affects the time and the cost.
Where we produce documentation during an engagement, including pinouts, measured operating parameters, control sequences and as-found configuration records, it is delivered with the instrument. It is your instrument and it should not be dependent on us to remain serviceable.
This is a laboratory decision, not a service-provider decision, and it turns on factors we are not in a position to weigh: capital cycles, grant timing, whether a current product actually fits the same experiment, and how much of the surrounding setup is built around this specific instrument.
What we can provide is the information the decision needs:
A failure analysis that lets a laboratory justify a replacement purchase is a legitimate outcome of a diagnostic engagement, and it is delivered in the same written form as a successful repair.
