Datasheet for #sb6267 DN
Recommendations:
Please read the User Manual and have a look at the FAQ at
http://www.alpeslasers.ch/?a=142
WARNING: Operating the laser with longer pulses, higher repetition rate,
higher voltage or higher current than specified in this document may cause
damage. 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).
