    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.

    D30 Signal Interface and Pin Description

    1(PWM Orange and white)

    RF Enable

    TTL logic input

    1=RF ON,0=RF OFF;1KΩ impedance.

    This input turns on the laser.(See also Pin 7,Control Enable, below)

    2(+15V Orange) +15 VDC±0.5VDC,0.25 A Max output for customer use
    3(Laser Green and white)

    Laser ok

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

    Output is asserted when no faults(SWR, Temp or Volt.)are detected

    4(Temp Blue)

    Temperature OK

    TTL logical output,1=Temp ok,0=Temp fault;

    Output is asserted when temperature is below 60℃

    5(Volt Blue and white)

    Power and voltage OK

    TTL logical output;1= voltage ok,0=voltage fault;

    Output is asserted when DC supply voltage is below max. value

    6(GND Green) For internal use. must be grounded
    7(Enable Brown and white)

    Control enable

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

    This input must be asserted before RF enable can be used to turn on the laser.

    8(GND Brown)




    1) The connector uses the RJ-45 type

    2) These specifications are subject to change
