1 Security Precautions
Before starting to work on the alignment procedure of the Littman/Metcalf laser system,
there will be two types of security precautions required, protection against laser radiation
and protection of the laser diode against electro-static discharge (ESD).
1.1 Radiation Protection
Make sure to provide adequate protection against laser radiation. E.g. protective eyewear
is absolutely required. Further precautions are required for higher power laser systems.
Consult your laser security officer for detailed instructions before removing the protective
cover of the laser head and before the starting the alignment procedure.
1.2 ESD Protection
Laser diodes are electro-static discharge sensitive (ESD) devices. Most premature laser
diode damages are caused by ESD damages. Make sure to take adequate precautions
against ESD. This can be done e.g. via a wristband which connects you to the laser
ground. Consult your security officer for detailed instructions before starting the alignment
procedure.
1.3 Protection of Optical Elements
The optical elements within the laser head are sensitive components. A simple finger print
will cause a irreversible damage. Do not touch an optical surface of any of the optical
components.
