*Additional heat sink or cooling fan may be needed to stabilize the output power of laser module if the laser module is operated continuously in a period of time.

** The expected life time of green laser module is based on the MTTF (Mean Time To Failure) rating of 808nm laser diode used in the green laser module.

The GMP-series 532 nm Diode Pumped Solid State Green Laser Modules, which use laser diode pumped Nd:YVO4 crystal coupled with KTP as a frequency doubbler, are designated solely as OEM components for incorporation into the customer's end products. Therefore, they do not comply with the appropriate requirements of FDA 21CFR, section 1040.10 and 1040.11 for complete laser products. 

Note: IEC 60825-1, EN 60825-1, and JQA require the laser products to meet Single Fault Failure Requirements, which require the highest emitted power under reasonably foreseeable single fault failure conditions never higher than the laser classification. Therefore, for class II or class 2 laser products, the output power is <1mW, the highest emitted power under reasonably foreseeable single fault failure conditions for this laser shall never be >1mW.
