1)
T
1
represent the initialization time of the laser machine. The initialization time is
less than 10s from power-on to perform initialization.
2)
T
2
represent the pump recharge time, usually around 5ms.
3)
T
3
represent the frequency switching time. Frequency needs to be adjusted before
optical laser output, and the switching time should not less than 5ms.
4)
T
4
2-8ms with external frequent mode, recommend 4ms.
5)
T
ON
represents the pulse build-up time. Usually the build-up time is less than 50 us
from the pump current raising up to reach the 90% power of the optical pulse.
6)
I
is the simmer pump current.
7)
P
means the height of the first pulse is adjusted by the pre-injection current I and
the reasonable height of the first pulse have been set before the laser leaves the
factory, which can meet the needs of most users. Special needs shall be put
forward in the customized contract.

PS
1
：
Pin 17 receives external DC voltage to provide power supply for inside
isolate chip of DB25. Therefore, please make sure Pin17 is connected to the +5V
power supply. The temperature warning will remain if the power or DB25 port is
not well connected.
2)
PS
2
: If the voltage or current states of the laser are abnormal, the alarm might
present
“
POWER ERR
”
due to using different marking card (for example:
Beijing JCZ Technology Co. marking card).
