 D: Frequency sampling time under internal frequency mode, at least 1 complete frequency
period before turning on the laser (PA).
 E: SIMMER value. The first pulse energy can be adjusted via GUI software.
Fiber laser control system self-locking: If fiber laser is on abnormal status (eg.frequency
signal<1khz, high temperature, low power supply etc.), it will stop working to protect the whole
system. Please restart the fiber laser and power on.
PIN2, 3, 22 Pulse Width Control
PIN2, PIN3 and PIN22 pins of DB25 control interface are not only used for basic control of
laser, but also for pulse width control. Table 10 shows the pulse width control pin and signal
description of M7 laser.

Serial Input
When fiber laser is serial input, setting data bits synchronize with
the rising edge of serial clock.

10kHz, 10KHZ is
recommended.

Pulse width control function:
High: Enable, Pin2 and Pin3 to control the pulse width
Low or Not connection: Disable
 Pulse width control instruction
 Send instruction to Pin2 of DB25 connector and send clock signal to Pin3 at the
same time. The instruction description will be transmitted in binary form, with its most
significant bit transmitted first.
 The instruction structure transmitted by the user to the laser is as follows:
 0xA5 (A5h) is the active pulse width control byte. 0xA5 and all subsequent data
bytes are input to Pin2 serial input.
 Data length of input laser is 4-bit bytes.
