POWER=###
This sets the output power of the laser. For example, to set a
power of 2800 mW, send the string POWER=2800, followed
by striking the RETURN key.*
POWER?
Returns the power of the laser (read from the internal
photodiode)
STEN=YES / NO
Enable (YES) or disables (NO) laser as default at start-up.
This serial command must be followed by WRITE
STPOW=###
### is the optical power in mW. Sets the default start-up
power. This serial command must be followed by WRITE
ACTP=###
### is in mW. Recalibrates the APC mode (See section 5)
WRITE
Stores APC calibration, STEN and STPOW in memory
LASTEMP?
Returns the temperature of the laser head in degrees
centigrade
PSUTEMP?
Returns the temperature of the PSU in degrees centigrade
STATUS?
Returns the status of the Interlock
TIMERS?
Returns the timers of the laser and PSU:
Time=#######.# Total time the system has been powered
Laser Time=#######.# Total time the diodes have been
powered
Laser > 1A Time=#######.# Total time the diodes have
been powered >1 A
VERSION?
Returns the timers of the laser and PSU:
* A minimum % current threshold level is required to achieve laser emission. This threshold varies from laser to laser and is
also dependent on the laser power. **The system has been tested for compliance using a 3 m serial cable. If a serial cable
>3 m is used, compliance of the system may be compromised unless optical isolation is used.
RemoteApp
Using Laser Quantum’s unique RemoteApp
software suite the laser can be controlled via the RS232 port. The application is
supplied on a USB Flash Drive and should install automatically. Alternatively, it can be downloaded from
www.laserquantum.com
. Follow the on-screen prompts to install the software onto the computer. RemoteApp
includes a
comprehensive instruction manual which can be accessed via the ‘Help’ and ‘Contents’ tabs.
The RemoteApp
can also be used if a remote connection is required by our Service & Support Centre and is a powerful tool
if performance optimisation is required.
Re-calibrating the laser power
The laser can be recalibrated at any time during its use to ensure the APC mode is in good agreement with any external
power meter device. Recalibration is a simple process that takes place via the RS232 port. The procedure for recalibration
requires the RS232 port to be configured for use with a terminal emulator (Section 5). The following procedure must be
followed:
1
Select an intermediate power that the laser is capable of reaching. Set the laser to this power by typing the
command POWER=###. “###” represents this intermediate or characteristic operating power level in mW.
2
After a period of 5 minutes, measure the actual power using a trusted, external power meter.
3
Type the command ACTP= [external power meter reading in mW].
