1. Laser power is tested according to the temperature of laser which is 25℃,everytime the laser temperature rises 1℃,the output power will reduce 1%.

2. Definition of stabilization: ±(Pmax-Pmin)/(2Pmax)

3. Testing condition of stabilization: Warming up about 10mins,controlling duty cycle constantly,under the normal operating environment.





D20 Signal Interface Description and Connector Pinout




( PWM+ orange white)

RF Enable

TTL logic input ;1=RF ON,0=RF OFF;1KΩ impedance;

This input turns on the laser. See Pin7,Control Enable


2(+15V orange)

+15VDC±0.5VDC,Max output for customer using is 0.25A



(Laser green white)

Laser status output

TTL logic output,1=LASER OK,0=LASER Fault;

When fault is not detected ,output valid

In case of temperature failure, the case temperature is below 60℃.



(Temp Blue)

Temperature status output

TTL logical output,1=normal temperature,0= Ultra high temperature;

When the case temperature is below 60℃, the output is valid.


(Volt blue white )

Power and voltage status output

TTL logical output;1=normal voltage;

0= abnormal voltage;


6(GND Green) For internal use. must ground connected


(Enable brown white)

Control enable

TTL Logical input;1= Laser control enable,0=Laser controlled shutdown

This input must be valid before RF is enabled to turn on the laser.


8(GND Brown) GND



1) The connector uses the RJ-45 type.

2) The color noted on pin can correspond to the cable color our company sent together with the product.
