Laser Diode Protection
Electrostatic discharge and current spikes can be a significant cause of damage
to laser diodes, but when proper precautions are taken, these risks can be
greatly reduced or eliminated. Arroyo Instruments’ controllers offer state
-of-art
laser diode protection, but no instrument can fully shield the laser from damage.
Please take these considerations into account when operating your laser:
1.
Always set the current limit at or below the maximum current your laser
can handle. This prevents the device from accidentally driving the current
too high, either via the set point or from the modulation port. This also
provides additional current limiting protection from ESD.
2.
Always work in an ESD safe operating environment, including the use of
wrist straps, ESD grounded work surfaces and floors, and ESD-safe tools.
3.
Where the AC power to the laser driver to temperature controller may be
noisy, use isolation transformers or uninterruptible power supplies that
provide isolation.
4.
Make sure all cables are securely connected and fastening screws are
screwed in tight.
5.
Do not route power cords or other cables in parallel with the laser or
temperature controller cables, as coupling may occur between the cables
and inject noise into the laser diode.
6.
While it is not possible to create a ground loop through the LaserSource
because of it’s isolation of all inputs,
it is possible when using other
equipment. Ensure that any other equipment is properly isolated to avoid
any ground loop problems.
