Features:
- Six Current Ranges
- User-Friendly Controls
- Built-In Laser Diode Protection Features
The ThorLabs LDC80XX Series Laser Diode Controllers are modular laser diode current controllers that provide "best in class" performance. All of these
current control modules have extremely low noise and drift performance, resulting in exceptional laser stability.
Six different current controller modules are manufactured,
with maximum output currents ranging from 100mA up
to 8A. The drive current can be set precisely with 16 bit
resolution - one part in 65,000. All current modules can
be operated in either constant current, or constant
power mode.
After installing a module into the PRO8000 chassis, the
front panel control screen is used to configure the plug-in.
The soft-keys are used to scroll through the slot location to
access the basic settings. The operational settings are
easily accessed; displayed mneumonic symbols and simple
prompts provide for user-friendly operation. All the settings
are retained in memory and automatically recalled upon
powering the mainframe.
The LDC8000 series current modules incorporate proven
laser protection features to safeguard sensitive laser
diodes. Besides common protection functions, such as
current limits, soft start and interrupt protection, an
advanced circuit design ensures that AC power-line
transients or power outage, as well as RF pickup cannot
affect the laser diode.
For each current module, three independent limits can be
set to safeguard the laser. Two of the limits are
programmable, which prevent the laser current and the
laser power from exceeding the user defined maximum
values.
The third limit is set via a recessed front panel trim-pot that
sets a "hard" current limit and protects against programming
errors and accidental adjustment of the front panel knob.
Even while externally modulating the laser it is not possible
to exceed either the hard or soft limits.
After activating the laser diode a soft-start function slowly
increases the laser current without voltage overshoots.
Even in the case of an AC power interruption, the laser
current remains transient-free. Voltage peaks on the AC line
are effectively suppressed by electronic filters, shielding of
the transformer, and careful grounding of the modules and
chassis. Our laser diode controllers have all been designed
by an engineering team that has a 15 year history of
building the high quality, user-friendly instruments. The
LDC8000 series meets the international requirements
regarding laser protection (e.g. CDRH US21 CFR 1040.10),
all models include a key-operated power switch, an
interlock, and a delay of the output current, plus many
additional features.
An analog control input enables the modulation of the laser
diode in constant current or constant power mode. The
maximum modulation frequency depends on the current
module used.
The LDC8010 Thorlabs Laser Diode Current Control Card may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
