Hi all ,
Just a quick question about lifespan hours on dpss 532nm modules .... When a manufacturer states for example 5000hours lifespan on module is this the lifespan on the pump diode or the KTP crystal or both ? .. Ive heard that the KTP can crystal can breakdown so to speak due to power below a certain wattage being pumped into the crystal causing electro chemical degredation ?
I recently opened up a 1w viasho module and upon carefull inspection and removal of the KTP crystal it literally crumbled to bits.
Just curious.
Cheers,
Brett
