General knowledge about laser technology
The concept of a laser was first invented by Charles Townes and Arthur Schawlow in 1958 while working at Bell Labs, but first laser was not built until 1960 by Theodore Maiman. Since that time many improvements and innovations have occurred, and today there are thousands of lasers being used in medical, industrial, telecommunication and defense applications. A laser differs from other light sources (flame, flashlight, lightbulb or LED) in that the light it produces is very directional or coherent. This allows the light to project in a beam or narrow cylinder instead of randomly illuminating in all directions simultaneously. Lasers also emit light over small ranges or at single wavelengths. The wavelengths can be attributed to colors of the light and are usually based on the laser type.
CO2 lasers can emit at 10.55um- 10.63um and 9.3um which is very deep in the infrared.

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/ D20I Signal Interface Description and Connector Pinout
|PIN NO||SIGNAL DESCRIPTION|
( PWM+ orange white)
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
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)
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.
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.
