LASER ON LED. This red LED comes on when water flow is established.
KEY SWITCH. Turning the key from off to
ON
position resets system logic and enables
power-up sequence to begin.
START/STOP. This button switch starts and stops the laser head flashlamp.
SHUTTER BUTTON. Depressing this switch to the
OPEN
position will open the intra-
cavity shutter on the laser bench and start lasing. Depressing this switch again will
CLOSE
the shutter. An audible click is heard when opening or closing the intra-cavity shutter.
DISPLAY READOUT LED. This digital display read-out shows all the error messages
and commands. The messages are explained on page 29 . The red VOLTAGE KV LED
and Q -SW DELAY
µs
LED light up when the DISPLAY LED shows their readings.
SELECT BUTTON
.
This button allows the user to step through the different operating
parameters which are explained on page 28 . The select ARROW UP and select ARROW
DOWN buttons are used to change the value of display parameters.
RS232 9-pin male plug. See page 40 for serial plug for RS232 operation.
EXTERNAL 9 pin female plug. The optional externals plug for a remote control device:
External interlock loop. See page 60 .
DAT (direct access triggering). See page 43 .
SINGLE SHOT. This connector accepts the Single Shot Cable (SS). When the SS is
plugged in you get one laser pulse each time one manually presses the SS fire button. When
the SS is disconnected the laser will fire at the last saved rep rate.
VARIABLE SYNC OUT. This connector provides a variable trigger output which is
adjustable via a pot to the right of VARIABLE SYNC OUT BNC on front panel of the
PCU. The signal provided is negative going TTL signal (3.5 V to 0 V into a 1
Μ
termination) that can be adjusted from 325 ns before lasing to 450 ns after lasing.
FIXED SYNC OUT. This BNC connector provides a negative going TTL signal (3.5 V to
0 V into a 1
Μ
termination) approximately 100 ns before laser pulse output.
FLASHLAMP SYNC. This BNC style connector provides a +3.5 V pulse at the start of
the firing of the flashlamp. This signal occurs ~180 µs before lasing output (depends on Q-
SWITCH DELAY setting).
Rear panel
DI IN. The distilled water input hose connector carrying warm water from laser head back
to cooling group.
DI OUT. The distilled water output hose connector carrying water from cooling group to
laser head.
