The LASer:OUTput command turns the laser output on or off.
Parameters
An <nrf value>; 1=on, 0=off.
Notes
There is a two-second delay after the output is turned on before the output shorting relay
is opened. Following this, the output current ramps up to the current setpoint slowly to
protect the laser. Therefore, the time to turn the output on and reach the setpoint current
varies from two to about three seconds.
After the output is turned on, it may be useful to wait until the output is stable (within
tolerance) before performing further operations, but it is not necessary. When the LASER
output is off, it is safe to connect or disconnect devices to the LASER output terminals.
When the LASER output is off, an internal short is placed across the output terminals.
Examples
"LAS:I 20; LAS:OUT ON" -action: sets the laser output current to 20 mA and then turns
the output on.
The LASer:OUTput? query returns the status of the laser output switch.
- where the response is 0 or 1
Notes
Although the status of the switch is on, the output may not have reached the setpoint
value.
Examples
"Las:OUT?" -response: 0, means that the output switch is disabled, devices may be
safely disconnected or connected at the LASER output terminals.
"LAS:OUT?" -response: 1, means that the LASER output switch is enabled, LASER
output is present.
