2 Getting Started
2.1 Parts List
Inspect the shipping container for damage.
If the shipping container seems to be damaged, keep it until you have inspected the contents
and you have inspected the ITC1xx mechanically and electrically.
Verify that you have received the following items within the package:
1. ITC102/110/133 OEM Laser Diode and Temperature Controller
2. Operating Manual
2.2 Operating Principle
The ITC1xx is an 100 x 160 mm board level controller that combines a low-noise, low-drift cur-
rent source with a precise TEC controller. Designed for easy integration into OEM applications,
these euro-sized boards are ideal for products or systems where excellent laser emission stabil-
ity is required. The analog interfaces offer easy access to parameter settings and readout.
These laser diode controllers support constant current (CC) and constant power (CP) modes,
as well as all laser and monitor diode polarities (CG/AG). The connected laser interfaces with
the controller through a 15-pin D-Sub connector. A fixed-ground-level design significantly im-
proves noise, transient suppression, and output stability. The laser operating current can be
modulated by an external control signal.
The built-in temperature controller includes a full PID feedback loop with independent P, I, and
D settings, which can be individually optimized. A wide variety of temperature sensors (such as
thermistors and the AD590 temperature transducer) are supported. A standard 64-pin PCB
connector provides access to output signals, analog control inputs, power supply connections,
temperature sensors and thermoelectric cooler elements.
A variety of safety measures allows an easy and safe operation of semiconductor laser diodes.
