It will result in loss of warranty, unless agreed upon with Alpes Lasers! WARNING: Beware of the polarity of the laser. This laser has to be powered with negative bias on the laser contact (= bonding pad, corresponding to the label ”laser” on the LLH) and the positive bias on the base contact (= submount, corresponding to the label ”base” on the LLH).
