Operation
27
The interlock LEDs are located on the front panel of the power supply.
The INTERLOCK LED will be illuminated when an internal or an
external interlock has been activated. The internal interlock is located in
the laser head. The laser head cover cannot be removed without
activating this interlock. The external interlock is located on the back of
the power supply, and can be put in series with a laboratory door or some
other circuit for safety purposes.
There are several controls and indicators on the control panel to make it
easy to operate the laser. Three knobs on the control panel are used to
set the flashlamp voltage, the repetition rate and to select the firing
mode. Three buttons on the control panel are used to stop the laser, fire
the laser and to put the laser into standby mode. LEDs on the
STANDBY and FIRE buttons indicate the actual state of the laser. A
LASER EMISSION LED serves as warning when the laser is enabled to
fire. An optional attenuator provides wide range energy adjustment
without affecting beam quality.
The Tempest Nd: YAG laser system is equipped with both internal and
external interlock switches. The interlocks are designed to ensure that
the laser is operated only when this can be done in a safe manner. The
internal interlocks ensure that the laser itself is safe and will not be
damaged. The external interlock can be used to ensure that the
surrounding facilities and people in the area are protected.
The Tempest Nd: YAG laser system has the following internal
interlocks:
1) Laser head cover opened
2) Control panel detached
3) Laser head umbilical detached
4) Cooling water temperature too high
5) Cooling water flow too low
The laser may be interlocked so that laboratory and room doors cannot
be entered while the laser is running continuously. The connector on the
back of the power supply may be wired so as to interrupt power to the
supply, thus disabling the laser. If the external interlock circuit is opened
the red INTERLOCK LED will be illuminated. To restart the laser, turn
the key switch to the OFF position to reset the external interlock switch.
