4 Turning ON the Laser
Safety
Before you turn ON the laser, ensure that you are completely familiar and follow
all safety information and recommendations stated within this document and the
document:
Koheras BASIK Safety, Handling and Regulatory Information
You must follow all safety regulations required at the location where the laser will
be operated.
Preparation
The laser is ready to be turned on when the following steps are completed.
1. The laser is securely installed and connected according to the procedures in
“Mechanical Installation” on page 87 and “Connecting the Laser” on page 91.
This means the laser should be installed in the recommended environment
with power applied and at the very minimum the door switch interlock.
2. The laser is connected to a PC using an RS-485 adapter and the PC has
CONTROL installed on it and executing according to the procedures in
“Communicating with the Laser” on page 47.
3. The FC/APC connector is placed so that any emissions are contained within
the working application such as a beam dump that can safely absorb the
emitted beam power.
Warning: Turning on the laser will emit hazardous laser Class 3B radiation. Ensure
to observe and implement all safety regulations, warnings and cautions in this
guide and the Koheras BASIK Safety, Handling and Regulatory Information docu-
ment before continuing.
Warning: Ensure the fiber connector face (tip) is clean. Optical power transmitted
through the connector may burn particles on the connector face damaging it.
Note: When connecting the output fiber patch cord, ensure to match it with an
appropriate fiber type.
Caution: Do not turn on the laser if it has been exposed to temperature and humidity
beyond the operating specifications. The laser is designed to operate in a non-con-
densing environment from +15°C to +60°C. Before turning on the laser, allow it at
least 30 minutes to stabilized at the operating room temperature. Turning on a laser
that is too cold or hot may lead to the system being damaged.
