    Default 40w chinese laser only works on around 25% power!?

    Hi,

    I have a 40w k40 chinese laser (UK based)

    I recently run the water to hot and the laser stopped working.

    I replaced the tube, and now the laser will only run on a power of 25%, if i turn the power slightly above that it will not run.

    Will i need a new psu? or is there somthing i may be missing?

    thank you in advance for any help!!

    Do you have a mA meter on the tube? It needs to be in series with the ground lead.
