System Control Electronics
The system control electronics, see Figure 7, consists of a laser control board, microprocessor,
hardware, software and associated wiring. This system switches the laser on and off, produces
pulses at the proper times, regulates pulse energy, ensures safety, provides appropriate controls
and status displays to the operator, and operates a variety of auxiliary subsystems, e.g., the water
circulation pump. The major components of the system control electronics and their functions
are detailed below.

Laser Control Board
The laser control board includes the microcontroller, as well as the digital and analog circuits to
control laser operation. The Control PCB for all three lasers is the same. Jumpers are used to
select for differences specific to a particular laser system.
The optical detectors for the internal monitor and the cal port reside on the front edge of the
control electronics PCB. The cal port detector is mounted direct to the control electronics PCB,
and is connected to the pick-off assembly. This configuration ensures that the fiber is not
affected when the Control Electronics PCB is lifted up for service access.
NOTE: On the
Apogee Elite system two detectors are used.
Microcontroller
The microcontroller is mounted on the laser control board. The software is on the board in flash
memory, which can be updated through a serial port.
