Fiber Laser Control - RD RDEncLas400G Manual

PWM control the laser power of laser
source and laser emission. L_AN only
control the peak pump current for laser
source.
LON_24V control the laser emission of
laser source. L_AN only control the peak
pump current for laser source.
Picture 3.3-2
We recommend users to use this connection shown as picture 3.3-2. Especially
in PSP mode, the laser on time is short and the laser spots are scattered evenly.
Laser power for single laser spot is neglected.

3.4 Fiber laser control

YAG laser should have several control signals that include of laser emission, repeat frequency,
pump current and FPS. The connection is shown as picture 3.4.
YAG has a complex control mode.
The laser emission signal used to
control the laser emission or not.
Repeat frequency is used to send
the modulate pulse to the laser
source. FPS is to kill the first pulses
and L_AN is to control the pump
current.
