QD-Q1yzz-L2 is a conductively cooled dual laser diode stacked array designed for very compact arrangement of stacks, each with 1 to 10 diode bars. These stacks are connected in series with very tight spacing between arrays. Other configurations are available (3, 4, 5 stacks).

The laser diode bar arrays benefit from fully developed technology, designed for improved efficiency and reliable operation.

Using AuSn hard solder technology, the assembly has been optimized to reduce thermal resistance. Using Quantel Laser Diode’s proprietary hard solder technology, different diode arrays can be packaged for customer defined heat-sinks. This enables the manufacturing of compact and complex customized pumping heads.

These stacks are ideal for pumping rods or slab solid state lasers for a broad range of aerospace, defense, industrial and space application.

• For a period of one (1) year from the date of delivery as stated in Article 4 hereabove, the Vendor warrants the Products against faulty materials and faulty workmanship except parts and components worn out during the normal use of the Products. During the above mentioned period, the Vendor's obligations shall be limited, at the Vendor's option, to the replacement or repair of the Product recognized as faulty by the Vendor which must be promptly return to the Vendor, carriage paid, together with full details of failure and certified. The repaired or new parts will be delivered free of charge to the place of delivery stated in Article 4.
• The Warranty of the Vendor will apply to the Products which have not been modified by the Buyer or a third party and which have been stored, installed, protected, maintained and used in accordance with the Vendor's specifications and instructions. Such warranty shall not apply in case of normal wear and tear or if the Products have been involved in an accident or subjected to any kind of misuse or detrimental exposure and in case of bad conditions of storage; or 
• if the Products have been submitted to abnormal conditions (mechanical, electrical or thermal) during installation or use; or, 
• if the defectiveness of the Products has resulted from exceeding the maximum values for usage (temperature limit, maximum voltage, etc...) defined by Vendor, from an incorrect choice of application or from a design made by the Buyer.
• Notwithstanding the foregoing, Vendor gives no warranty whatsoever with regard to experimental, developmental or non-qualified Products.
  The foregoing constitutes the whole and sole warranty given by the Vendor and shall be in lieu of any other warranty; in particular, the Vendor does not warrant the suitability or fitness of the Products for a particular purpose, nor that the functions of the Products may be used in any application or combination which the Buyer may choose.
