Places the LDX-36000 in QCW-Pulse output mode.
None.
If the output was enabled when the command is given, the output will be disabled prior to
changing modes. If the command is given when the instrument is already in the
specified mode, output will be disabled.
In this mode, pulsewidth, frequency and duty cycle are controlled either from the front
panel or via GPIB.
"LAS:MODE:PULSE" -action: output is disabled if it was on and the output mode is
changed to QCW-Pulse.
Places the LDX-36000 in QCW-Trigger output mode.
None.
If the output was enabled when the command is given, the output will be disabled prior to
changing modes. If the command is given when the instrument is already in the
specified mode, output will be disabled.
In this mode, pulsewidth is controlled either from the front panel or via GPIB. Pulse rate
and duty cycle are controlled by an external trigger input from the rear panel BNC.
"LAS:MODE:TRIG" -action: output is disabled if it was on and the output mode is
changed to QCW-Trig.
Enables or disables current source output.
An <nrf value>; 1 = on, 0 = off.
There is a two-second delay after the output is enabled before the shorting relay is
opened and current begins flowing. Following this, the output current slowly ramps up to
the current setpoint to protect the laser (CW mode only). Therefore, the time to turn the
output on and reach the setpoint current varies from two to approximately three seconds.
After the output has been enabled, it may be useful to wait until the output is stable
(within tolerance) before performing further operations, but it is not necessary. When the
output is off, it is safe to connect or disconnect devices to the output terminals.
When the output is disabled, an internal short is placed across the output terminals.
"LAS:LDI 7.5; LAS:OUT ON" -action: output current setpoint is set to 7.5 amps and the
output is enabled.
"las:out 0" -action: output current is disabled and output shorting relay is closed.
