Datasheet for #sbcw6269 UP
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 higher current or voltage than specified in this document may cause damage and will result in loss of warranty,
unless Alpes Lasers has permitted to do so!
WARNING: Beware of the polarity of the laser. This laser has to be
powered with negative current on the laser contact (= bonding pad, corresponding to the label ”laser” on the LLH) and the positive current on the
base contact (= submount, corresponding to the label ”base” on the LLH).
To use with a power-supply ILX Lightwave LDX-3232 or equivalent.
