    Default Testing dodgy 532nm DPSS units, any DPSS Guru's on PL.

    Just testing a load of heads which have varying failures; All chinese 1W-2W 532nm DPSS

    Most of them are outputting power to spec but some have a strange beam profiles.

    On one as an example; when pointing at a wall the spot looks more like a comet; ie has a spot with a tail.

    On some the spot is more like a line.

    I suspect it is crystal failure/alignment issue as they are giving around the right output power; Also I checked the output optics for cracks and all seam to be fine.

    Anyone seen these faults before, any obvious clues to what could be failing?
