4.7.2 Internal control mode
5) Turn the key switch to the “ON” position and the “Power” indicator on the front panel
light on;
6) Waiting for 10s until the internal main control board circuit initialization is completed;
7) Set the power of the laser (the power is set by 0-10V analog single when the AD mode
is enabled, and the power is set by the PC software when the AD mode is disabled.);
8) Press the “Laser” button ( enable hardware emission)on the front panel;
9) Send the start or stop emitting command to control the emission via RS-232.
See 4.8 to get the process of laser shutting down.
4.7.3 External control mode
Modulation Mode: When the duty cycle of the internal frequency is set to 100%, the laser
operates in external modulation mode. The laser is controlled by the user's "modulation" signal
provided by the external MOD interface. For the time sequence diagram, see [4.6.4 Control
sequence diagram]
Gate Mode: When the duty cycle of the internal frequency is less than 100%, the laser
operates in Gate mode. The laser is controlled by the MOD signal and internal frequency. MOD
signal is used to start and stop internal pulse signal. For the time sequence diagram, see [4.6.4
Control sequence diagram]
The laser operates on external modulation mode by default.
5) Turn the key switch to the “REM” position (or turn the key switch to OFF, short the
SERVICE interface PIN 1, 2) and the “Power” indicator on the front panel light on;
6) Wait for 10s until the internal main control board circuit initialization is completed.
7) Set the power of the laser (the power is set by 0-10V analog single when the AD mode
is enabled, and the power is set by the PC software when the AD mode is off.);
8) Give the emission enable signal in one of the following ways:
