    Default LasIT 50W diode pumped Nd:Yag Head not lasing

    Dear all,
    I am trying to resurrect an nd:yag laser head manufactured from LasIT :
    it is a 50W Q-Switched unit, side pumped by 4 Laser Diode Bars.
    I have removed the q-switch and aligned (many times) the mirrors with an HeNe and a target at arount 1mt from the crystal (the unit was dismounted so the alignment was lost), but when I power the diodes with a precision regulable current source ( I have tried from 0 to 20Amps ) laser diodes light up but the crystal won't emit..

    Someone have experience with this kind of head or have some suggestions ?

    Thank you very much..

    Best Regards,
    Massimiliano Carli
