3.1 Prerequisites
Storage
All ALPES LASERS lasers are delivered in a hermetic waterproof storage box, shown
in figure 3.1, in which the laser chip is held with pins. This box should always be
used when storing the laser out of its housing. The laser chip is soldered to the pads
using In soldering, which melts at 120
◦
C, therefore the storage temperature should
not exceed 80
◦
C.
Figure 3.1.: ALPES LASERS QCL storage box.
QCLs can be stored at ambient temperature (10 to 30
◦
C) in normal atmosphere.
Humidity should not exceed 80%, and condensation is to be avoided. The laser must
be operated in a dry atmosphere below 50% relative humidity. If possible, it should be
completely dried using a desiccant material or by flushing with N
2
.
CAUTION:
Even when packed, ALPES LASERS equipment should not be exposed to rain,
snow or direct sunlight. Extreme temperature changes must be avoided.
