Syneron-Candela GentleLASE
Syneron-Candela · Model GentleLASE
Speed - Treat more patients faster and more comfortably with the largest spot size and fastest repetition rate found on any hair removal laser. Efficacy - 17,666 watts of peak power enables the GentleLASE to treat a variety of conditions unlike any other laser on the market today. The GentleLASE is capable of delivering 755 nm fluences up to 100 J/cm2 in pulse durations of 3 ms for unparalleled treatment efficacies in hair removal - especially thinner, finer hairs other hair removal lasers simply cannot touch - and the treatment of pigmented and vascular lesions and wrinkles. Patient Comfort - Subject your patients to fewer laser pulses and provide them faster treatment times using the GentleLASE’s 18 mm spot size, the largest spot found on any hair removal laser. Patented Epidermal Cooling - Candela's Dynamic Cooling Device represents an adjustable epidermal protection technology to maximize patient safety and comfort. Integrated computer controls assure consistent, reproducible protection, regardless of who is operating the laser for true treatment independence and ultimate patient safety.
Key tips
- ·Verify true laser output with an external power meter, not the console readout - the display drifts independently of real delivered energy.
- ·Never bypass a door interlock, key switch, or footswitch safety to finish a treatment - laser safety interlocks are not optional.
- ·Most low-output complaints trace to the delivery fiber or handpiece, not the laser source - inspect and swap those first.
- ·Intermittent mid-treatment shutdowns are usually cooling-related - check coolant level and flow before suspecting the diode or lamp.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
No or low laser output
HighSymptoms: Weak or no output at the delivery device, treatment ineffective, power not reaching the set value.
Root cause: Laser module / lamp / diode-bar ageing, a damaged delivery fibre / handpiece / applicator, or a driver / power-supply fault.
Cooling / thermal shutdown
HighSymptoms: Unit shuts down after a period, over-temperature or low-flow alarm.
Root cause: Chiller / TEC fault, low or contaminated coolant, a failed pump, or blocked airflow.
Delivery fibre / handpiece / applicator fault
MediumSymptoms: Burn marks at the tip, high loss, intermittent output, applicator not recognised.
Root cause: Damaged or contaminated fibre / applicator / connector.
Skin-cooling / contact-cooling fault (aesthetic)
MediumSymptoms: Skin cooling not delivered, cooling / cryogen alarm.
Root cause: Contact-cooling / cryogen supply, a valve, or the tip.
Footswitch / interlock / key fault
MediumSymptoms: Laser will not fire, key / interlock / footswitch error.
Root cause: Footswitch, door interlock, or key-switch fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Laser output power verification against a calibrated external power meter
- ·Cooling-system check: coolant level, flow rate, and filter / heat-exchanger condition
- ·Delivery-system inspection: handpiece, delivery fiber or articulated arm, and output optics
- ·Interlock, key-switch, emergency-stop, and footswitch function test
- ·Beam-alignment and optical-path check per the service manual
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No or low output
- Measure output at the delivery device with a laser power meter against the setting.
- Fit a known-good delivery fibre / handpiece / applicator.
- Confirm the cooling system runs and coolant is at level and clean.
- Check the key, interlock and footswitch are satisfied.
- Escalate a confirmed laser-module or driver fault to the OEM; recalibrate power after any module work.
Symptom: Thermal shutdown
- Confirm the cooling fans / pump run and airflow is clear.
- Check the coolant level and replace the coolant filter.
- Let the unit cool and restart.
- Clean the air filters / vents.
- Monitor for recurrence during a treatment.
