Datasheet for #sb554 DN
Recommendations:
Please read the starter kit user manual (at least installation chapter 5), if
available, and have a look at the FAQ at http://www.alpeslasers.ch/alfaq.pdf
WARNING: Operating the laser with longer pulses, shorter period, or
higher voltage or current than specified in this document may cause damage
and 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).
