    a new LF347 fixed things for the thermal regulation, next step for me is getting a decent LPM and realigning it from the start

    I was wondering if any one knew what the trim pots on the driver do, I have realigned this laser twice, I think they should have epoxied the screws but oh well, I got it back to 840mw from 1 watt, the first time I aligned it I got the full output power but now I cant get more then 840 and the sticker over the trim pots may have been twiddled a bit as this laser has changed hands a few times, it has a VD-II driver

    since this laser has no optical feed back loop I am thinking the pump diode's output is a little less then it was
