Lee Laser, Inc., warrants that Series 600, Series 800 and Series LDP Nd:YAG Lasers, and Series LEP DPSS Lasers shall be free from defects in materials and workmanship for a period of one (1) year from the date of delivery. This warranty is limited to the adjustment, repair, and/or replacement of defective parts when the defective equipment is shipped to Lee Laser, transportation prepaid, prior to the expiration of the warranty period. Charges for return transportation of the equipment to the customer will be billed to the customer by Lee Laser.

Lasers purchased by OEM customers (for integration into laser machining systems) are warranted for a period of one (1) year from the date of delivery to the end user, not to exceed 15 months from the date of shipment from Lee Laser factory.

The warranty becomes void if:

  1. the equipment is operated in a manner other than that prescribed by Lee Laser in the Operation Manual, and/or supplements thereto.
  2. the equipment is operated in a manner that is not in conformance with purchase specifications and specifications contained in the Operation Manual, or supplements thereto.
  3. the equipment is not maintained in accordance with procedures in the Operation Manual, and/or supplements thereto.
  4. the equipment is repaired, altered or modified in any way by other than Lee Laser authorized personnel, or without Lee Laser authorization.Optical coatings on mirrors, Q-switches and YAG rods are warranted against defects in materials and workmanship, but not against operator misuse or abuse (such as laser burns from unclean surfaces). Harmonic generator crystals (LiIO3, KTP, LBO) are not covered under warranty. These are considered to be long-term consumable items, subject to localized deterioration and eventual failure even during normal use.

Consumable parts (arc lamps, flow tubes, filters, etc.) are warranted against defects in materials and workmanship, but are excluded from the 1-year warranty period of the original equipment. Laser parts purchased outside the original warranty period are warranted for a period of ninety (90) days.

Special Warranty for Series LDP, Diode-Pumped Nd:YAG Lasers

Diode Pump Modules (Diode Modules) of Series LDP Nd:YAG Lasers are warranted against defects in materials and workmanship for a period of one (1) year (up to 15 months for Series LDP lasers that are purchased by OEM customers) or 5000 hours from the date of delivery of the laser to the original purchaser, whichever occurs first.

During the warranty period, the Series LDP Nd:YAG Lasers should be expected to maintain an output beam power level not less than 90 % of the lasers’ specified output power capability solely from diode laser aging or failure. This normal reduction of laser output power may be corrected by a gradual increase in laser diode current as the laser output efficiency lessens.

The decision for repair or replacement of the Diode Module, either under warranty or not under warranty, should not be based solely on the output beam power level of the Series LDP Nd:YAG Laser. There are many defect conditions that can result in reduced laser beam power output, only one of which is diode laser damage or failure. Customers that suspect damage or failure of a Diode Module should contact Lee Laser, and report all details. Lee Laser may request more information before we make a preliminary determination that the Diode Module may be at fault. Final determination about repair or replacement of the Diode Module will require return to Lee Laser and inspection for damage.

Rebuilt Diode Modules contain all new diodes, and are warranted against defects in materials and workmanship for a period of one (1) year or 5,000 hours from the date of shipment, whichever occurs first. Repaired Diode Modules may retain some of the original diodes that have yet to reach the end of their lifetimes, and are warranted only for the remainder of the laser s warranty period.

In any case, during the warranty period Lee Laser will be the sole judge as to whether the Diode Module requires repair, rebuild or replacement, and what constitutes warrantable damage.

Special Warranty for Series LEP, End-Pumped Nd:YAG Lasers

The Diode Pump FAP Assembly of Series LEP Nd:YAG Lasers is warranted against defects in materials and workmanship for a period of one (1) year (up to 15 months for Series LDP lasers that are purchased by OEM customers) or 8000 hours from the date of delivery of the laser to the original purchaser, whichever occurs first.

During the warranty period, the Series LEP Nd:YAG Lasers should be expected to maintain an output beam power level not less than 90 % of the lasers’ specified output power capability solely from diode laser aging or failure. This normal reduction of laser output power may be corrected by a gradual increase in laser diode current as the laser output efficiency lessens.

The decision for repair or replacement of the Diode FAP Assembly, either under warranty or not under warranty, should not be based solely on the output beam power level of the Series LEP Nd:YAG Laser. There are several defect conditions that can result in reduced laser beam power output, only one of which is diode laser damage or failure. Customers that suspect damage or failure of a Diode FAP Assembly should contact Lee Laser, and report all details. Lee Laser may request more information before we make a preliminary determination that the Diode FAP Assembly may be at fault. Final determination about repair or replacement of the Diode FAP Assembly will require return to Lee Laser and inspection for damage.

Replacement Diode FAP Assemblies contain all new diodes, and are warranted against defects in materials and workmanship for a period of one (1) year from the date of shipment from Lee Laser. Damaged Diode FAP Assemblies cannot be repaired. In any case, during the warranty period Lee Laser will be the sole judge as to whether a Diode FAP Assembly requires replacement, and what constitutes warrantable damage.

Factory Training

Laser equipment is very expensive to purchase and repair. Failure to properly operate and maintain this equipment can be costly to the end user. Therefore, Lee Laser always recommends factory operation and maintenance training to all new customers that purchase our equipment.

In addition, from past experience Lee Laser knows that customers that receive factory training typically experience fewer problems with their lasers, either during the warranty period or after the warranty period.

This is especially true of some specific products such as the Series LDP Diode-Pumped Nd:YAG Lasers and LBO harmonic generators. The operation of the Series LDP lasers is significantly different from the lamp-pumped Nd:YAG lasers with which many customers already may be familiar. Lee Laser believes that without some factory training in the operation and maintenance of these lasers, there is an increased possibility that some problem can develop because of improper operation or service. The same is true of the LBO harmonic generators that are used on visible laser models.

To avoid such a situation, Lee Laser requests that all customers that purchase such equipment send an engineer or technician to Lee Laser for one-day of training. It will be the responsibility of that engineer or technician to, in turn, provide operation and maintenance training to the customer’s other technical and end-user personnel.

Lee Laser will not ship a Series LDP laser or laser that contains an LBO harmonic generator until such time as the customer’s engineer or technician has received this factory training.

Warranty Claims

If claims under this Warranty become necessary, contact Lee Laser for instructions and issuance of a Return Materials Authorization (RMA). Equipment will not be accepted for warranty purposes unless the return has been authorized by Lee Laser.

Laser parts or components repaired or replaced under warranty bear the same warranty expiration date as the original equipment.

Use of unauthorized replacement parts may void the warranty. In all cases, Lee Laser will be the sole judge as to what constitutes warrantable damage.
