Background
The Compass 315M laser is a diode-pumped,
solid-state, continuous-wave (CW) laser that is ideal for a variety of
research and classroom instruction applications. The lasers
are
modular components that are often sold for use in OEM equipment, and
often require additional thermal management and/or an analog controller
(or an interface to the controller) to assure adequate cooling and to
provide the drive electronics for the laser head.
Objectives
Design the
interface electronics to a Coherent analog controller for
the 315M laser head using the 15 pin DB15M connector. The
control
panel should be designed using a PCB layout, include fault indicators,
as well as initialization logic for the laser. The
initialization
logic should indicate when the laser has stabilized, when the selected
power level has been achieved and has been locked in, and provide an
LCD display indicating the current operating power of the
laser.
The control panel should also provide monitoring of the laser diode
current and the current control voltage, as necessary.
