A. Electrical connections
The
MOA
has a single electronic circuit board for interfacing between the
device and a laser driver/controller, whereas the
MSA
has an additional
board for also operating the seed laser/controller. For information on the
seed laser, please refer to the seed laser user manual. The information
below relates to the amplifier interface only.

MSA
The amplifier is connected to a controller via a B1048, B1055 or B1056
headboard (figs. A.1, A.2) which provides connections to the
TA
diode,
TEC
,
and a passive NTC thermistor temperature sensor. Connections from the
B1048, B1055 boards to the components use Hirose DF59 “swing-lock”
wire-to-board connectors; B1056 uses JST EH-series connectors. There
is also a photodiode amplifier which can be used to generate a signal for
monitoring the laser output. The boards include a solid-state protection
relay, passive protection filters, and a laser-on
LED
indicator.
