1. Principle
of adjusting laser power
A TTL compatible signal must be
provided to the laser of the power and signal connector to drive the laser.
Output power can be controlled from 0 to 100% (CW Mode) by pulse width
modulation of the input signal. The output laser power is proportional to the
duty of the PWM signal.
In our controllers, the frequency
is fixed at 5kHz (0.2ms). Adjusting the output laser power means adjusting pulse
width T1.
2. STCB
series integrated laser controller
CO2 laser controller provides DC
power supply of CO2 laser, control I/Os and laser power adjustment. It is
integrated with a 19� control panel. Its main specifications are
-
Model: STCB28-xxxx (xxxx: CO2
laser model such as ULR10, ULR50 etc)
-
Provide DC power supply
according to the lasers (ULR10, ULR30, �) (optional)
-
Laser power adjustable from 0
to 99% of the maximum laser power
-
Two control methods
available: manual and auto
-
Under the manual method, a
potentiameter on the panel is used to adjust the laser power and a button is
used to switch on/off laser
-
Under the auto method,
external signal TTL is used to adjust laser power, laser pulse repetition
rate and laser beam on/off
-
Dimension (LxWxH):
500x302x100mm
3. STCBV
series compact laser controller
This compact laser power
controller is used to digitally modulate the RF amplifiers that excite the
plasma within the resonating chamber of the laser. This is accomplished by using
a clock frequency square wave of 5kHz and varying the duty cycle of that square
wave from 0 to 99%.
The main specifications are:
-
Power input: +5VDC
-
Signal output: 0-99% duty
cycle PWM 5kHz
-
Gate input (default logic
low): TTL logic (High +5VDC, Low 0VDC)
-
Clock frequency: 5kHz +/-%
accuracy
-
Enable input (default logic
low): TTL logic (High +5VDC, Low 0VDC)
-
Two control methods
available: manual and auto
-
Dimension (LxWxH):
6.26x4.125x1.5inch (159x105x38mm)
-
Weight: 12.3 ounces (0.349kg)
