Figure 16 PULSE mode Operational range
4.5.1 Operation Sub-modes
For CW and PULSE mode of laser emission, there are three operation sub-modes:
Standalone, Modulation, Gate. There are two ways to set the power level: either digital (RS-232
or Ethernet) or via external analog voltage (Analog Power Control enabled). There are also two
ways to enable/disable the laser emission: either digitally (RS-232 or Ethernet) or via the signal
applied to the pins 7-9 of the DB-25 interface connector.
Standalone (Modulation and Gate Disabled)
The emission starts/stops by
:
1) command of “EMON” and “EMOF” via RS-232;
2) command of “EMON” and “EMOF” via Ethernet;
Modulation
The emission starts/stops is performed by means of the modulation signal applied to the
pins 17-9 of the DB-25 interface connector under the assumption that emission has been enabled
before.
Gate
Pulses are generated internally with parameters set by sending corresponding commands via
RS-232 or Ethernet. Start and stop of the pulse train is controlled by means of modulation signal
