    Hehe sorry I'm pretty tired.
    I will have a look right now though!

    I do not have the right measurement equipment to measure temperature
    So I'm unable to do this, also I have no clue where to get this.
    How much *preferably in the netherlands* would it cost to get this blue DPSS module retuned?

    You do not need to measure temperature, you need a power meter. But we can give it a try on the next lem

    DPSS was measured wrong and had a warmup time of 15 minutes. I also cleaned my optics and power should have likely increased *measurement wasn't made from the laser output directly.

    Oh...OK I guess I have been building DPSS lasers wrong all these years. I have several temperature data sheets on actual LBO and BiBo crystal temp ranges for SHG of type 1 and type 2 from several manu's. The quality of A/R coatings also have an important factor in a bulk laser's power production. And I guess I wasted my time temperature tuning diodes for max PO at a given amperage......have fun and good luck. BTW I thought the 532nm laser was in question ? Now I see a post of the blue with an issue as well? Strange days indeed.

    oh no it was the blue that was outputting lower power.
    So i thought.
    I've been told today the measurement was likely unreliable. Not only did I clean my optics extra today *they were really filthy after all* and also it wasn't measured directly from the laser module but after the apperture with no 15 minute heatup.
