MOGlabs CEF, Manual

2. First light
Mount your laser to an optical table using the screws provided. Your
laser has been carefully tuned to the specifications given in your laser
test report. Please make sure as you continue with this manual, that the
diode injection current, temperature and piezo offset ( FREQUENCY ) match
those of the test report.
It is assumed that a
MOGL
abs
DLC
controller has been provided with your
laser. If a third party controller is used, please set a current limit according
to the maximum safe operating current stipulated in your test report.
For longer wavelength lasers, an IR upconversion card or CCD camera
without IR filter can be very helpful. Common low-cost security cameras,
computer USB cameras, and home movie or still cameras are also good
options, although they often have infra red filters which may need to be
removed.
2.1 Standby/Run
Please first check that the MOGL abs DLC has been set to the correct mains
supply voltage by inspecting the red voltage selector above the rear panel
IEC power inlet. Then turn the main power switch on. Make sure that the
laser diode current supply (( CURRENT ) knob) is turned fully anti-clockwise,
and that the OFF/MOD switch, and that the SLOW and FAST lock switches
are off (up), and then turn the keyswitch from STANDBY to RUN . The LED
status indicator should be yellow indicating that the thermistor and TEC
elements are connected.
2.2 Current
Turn the laser diode CURRENT adjust to zero (fully anti-clockwise). Note
that it is not recommended to turn the current to zero when turning off the
laser: the soft-start function of the DLC ensures that the current is ramped
