Green Diode-Pumped Solid-State Laser Systems (Hardware)

Operating Your System
Main Power (indicator): This indicator is lit green whenever ac power is
applied to the system and the Laser Enable/Laser Disable key switch is in
the Laser Enable position.
POWER (connector): This 5-pin female connector is attached to the
Power Cable connector from the laser head.
RS-232 (connector): This female DB-9 connector on the front panel of
the power supply allows the laser to be controlled remotely from a
personal computer or other device equipped with an RS-232C serial
interface. The pin connections are described in Table C-4 in Appendix C.
The RS-232 command set and syntax is described in the DPSS Software
Reference.
SIGNAL (connector): This DB-25 female connector is attached to the
Signal Cable connector from the laser head.
System Fault (indicator): This indicator blinks in groups when there is
an out-of-tolerance condition in the laser or if the safety interlock
connection is broken. If this indicator is lit, the laser will not start, or, if
the laser is on, it will immediately shut off. The number of blinks in a
group indicates the nature of the fault.
1 blink: Interlock open
2 blinks: Compliance limit error
3 blinks: Base Temperature error
4 blinks: Crystal Temperature error
5 blinks: Laser Temperature error
6 blinks: Power Supply error
7 blinks: Hardware Read error
