LASER CONTROL OUTPUT

Clipper’s Option 11 consists of a programmable lattice chip which can be programmed based upon
customer’s requirements. The main objective for this option is to be used as a laser controller. Different
programs can be loaded in this chip based upon customers’ requirements and each code will be designated
an alpha-numeric suffix after options number if the code is developed by Delta Tau and can be ordered at
a later time with the same suffix.
Clipper’s option-11A is developed as a general command signal needed for CO2 lasers. Usually CO2
lasers require a few digital I/O signals in order to control the status and mode of the laser and a control
signal, which based upon the signal features controls the output power of the laser. The laser can be in a
few different modes:



Disabled



Standby



Active

Controlling between disabled mode and other modes is usually done through a digital output, either
directly if the device is TTL level or it would have to be done through a relay system. The difference
between the “Standby” mode and “Active” mode is because of the signal type and shape. Usually in order
to control the output power of the laser, a PWM (Pulse Width Modulation) signal is used and the positive
duty cycle of the signal indicates the output power of the laser, varying from 0 to 100%. However, in
order to ensure immediate response from the laser when an output is required, the gas needs to be kept
ionized. This can be achieved by outputting a PFM signal. The frequency and duty cycle required for each
of these modes differs based on the laser model and size and should be adjusted accordingly.
Assuming the following graph is the laser output response to a step command, the frequency of the
modulation can be selected.

As you can see, the rise time for the laser is about 126μsec. This means in order for our modulation to
fully cover the 0 to 100% range of the output, the frequency should be set close to 1/126μsec = 7936 Hz
or 8kHz. The tickle pulse is required in order to reduce the time between the change of command to PWM
and actual output of the laser. However calculating the signal requirements for the Tickle pulse is
