North American engineering support for out-of-warranty EKSPLA systems: Atlantic, PL and SL series, FemtoLux, LightWire, NL nanosecond and NT tunable families. Component-level evaluation on the bench in New Jersey, on Eastern time. You get written findings before any repair, and nothing is repaired without your written approval.
EKSPLA is a Lithuanian manufacturer of picosecond and nanosecond lasers and tunable parametric systems, and the equipment is well regarded. Its published scientific service department is in Vilnius, and its US branch publishes an orders contact.
We are in Parsippany, New Jersey, on Eastern time. For an out-of-warranty system, that means an engineer who can look at your measurements the same working day, a bench inside the United States, and no transatlantic crating cycle in the middle of a diagnosis. Where EKSPLA can resolve your problem directly, use them. Where you need a domestic option, this is what we do.
A written diagnostic scope with a fixed fee before anything ships, findings in writing before any repair is quoted, and no repair, substitution or modification without your written approval.
We provide independent service and repair support for the families below. What a specific system needs is settled by its configuration, its parts access and the measurements the project requires, and we confirm that with you before anything ships.
Send us your configuration and we will confirm the scope. On these platforms the pump pairing, the generation of the control electronics and the parametric or harmonic modules fitted matter more than the family name, and we settle both at the enquiry stage rather than after you have paid to crate the system.
On the NT tunable and PG parametric families, the first measurement. A parametric section cannot exceed what the pump delivers, and pump energy, pulse duration, beam quality and timing all matter at once.
On the seeded picosecond platforms, the driver that defines pulse amplitude and timing. A failure here produces a system that is electrically and thermally perfect and optically dead.
Driver failures, protection trips and degraded diodes, frequently silent, with the control layer reporting no error while holding a limited state.
Gain stages and the optics and fiber interfaces between them. Damage at a single interface removes the output with no electrical trace.
Pockels cell assembly, driver and timing, and hold-off behavior.
Crystals, ovens, temperature control and separation optics, assessed only after the fundamental reaching each stage has been measured.
On NT and PG systems, stages that will not move or no longer track readback, and calibration tables that map a requested wavelength onto hardware positions. A lost table presents as a tuning fault with healthy hardware.
TEC loops, sensors, drivers, chillers and flow. Presents as a silent power limit far more often than as a temperature alarm.
Monitor photodiodes, conditioning, converter stages and the control loop, in both failure directions.
Controllers, serial and Ethernet interfaces, and the control software including LabVIEW and MATLAB integrations.
Send the model, a photograph of the product label and the symptoms. We review it and respond with the next step.
Every job runs on a written scope. The order below exists to eliminate a branch cheaply before the next, more invasive step is justified.
Every engagement names its measurements before it starts. PhaseX defines and provides the measurement capability the project requires. Depending on the system and the question being answered, that is owned, rented or qualified third-party measurement resources arranged as required. The evaluation proposal states which measurements will be made, by what method, and where each one comes from, together with the acceptance criteria the work is judged against.
| Measurement | What it establishes |
|---|---|
| Drive current against command | Whether a commanded setpoint reaches the driver and produces real current, which separates a control-path fault from an optical one |
| Supply, rail and protection behavior | Rail integrity under load, sequencing, and protection states that cap output without reporting anything |
| Timing, trigger and switching | Trigger and synchronization paths, driver and Pockels cell switching, and pulse-train structure |
| Optical power and pulse energy by wavelength | Real output at each wavelength on a defined and terminated path, with the detector, wavelength response, attenuation and measurement point stated |
| Optical pulse presence and repetition rate | Whether an optical pulse train exists at all, and its relationship to the trigger |
| Spectral condition | Emission wavelength and bandwidth, and confirmation that the light being measured is the light assumed |
| Beam and mode condition | Spatial condition of the output, and evidence of optic, fiber or alignment damage in the delivery path |
| Thermal behavior under load | Cooling loops, TEC and oven control, and thermal derating that presents as a silent power limit |
| Pulse duration and beam quality | Specified where the project requires it, and performed with the measurement resource identified in the proposal |
In-house instrumentation currently includes a RIGOL MHO984 oscilloscope and a Joulescope JS320 for electrical, current, timing and pulse-train work. Optical metrology is specified per project and provided through owned, rented or qualified third-party measurement resources arranged as required and named in the proposal. We do not publish an equipment inventory in place of a measurement plan, and we do not offer manufacturer-equivalent calibration or certification to original published specifications where the original acceptance data and the corresponding standards are unavailable.
A system that cannot be brought to its normal operating state on the bench cannot be diagnosed. For bench evaluation we normally need:
On discontinued platforms the customer's own paperwork is frequently the only surviving record of the configuration. Send it even when it looks irrelevant.
We receive systems from outside the United States, including from Canadian universities and research institutes. We provide the commercial documentation a repair shipment normally requires and coordinate with your shipping office. Customs classification, duties, temporary import treatment and clearance timing remain the sender's responsibility, and we do not give customs guarantees. Insurance is the sender's decision and should reflect replacement value. We document the as-received condition on arrival, which is the evidence you would need if transit damage has occurred.
We are direct about the work we take on, so we are equally direct about the two boundaries.
If your system is still inside its manufacturer warranty, use the manufacturer, or get written authorization from the seller first. Our work is out-of-warranty and legacy equipment, which is where the support gap sits in any case.
Class 4 work is planned and executed under a project-specific laser safety plan. The required engineering controls, personal protective equipment, beam management and facility conditions are defined in writing before any energized optical work begins, and the infrastructure that plan calls for is provided within the project scope. Where a laboratory's own controls are involved, final hazard analysis and approval stay with the institution's LSO or EHS function.
PhaseX Laser Services is an independent third-party service provider, not affiliated with or authorized by any manufacturer named on this page unless expressly stated in writing. Brand and model names identify equipment only.
On the NT and PG parametric families the pump measurement at the module input decides where the fault sits. On the seeded picosecond platforms the question is whether commanded current produces actual current. Send label photographs and what the system does now.
