Laser diodes are manufactured in many different housings. Normally the following components are
installed together in the housing of the laser:
· Laser diode
· Monitor diode
· TEC element for setting the chip temperature
· Temperature sensor
The laser diode and the TEC element are always sourced against ground by the ITC8000. This is
of a considerable advantage with respect to the protection of the connected devices and to the
current stability.
The modules have a monitor diode input that is set up as a transimpedance amplifier input (input
impedance 0 W). The monitor diode input can be operated without or with bias voltage (0 V...10 V).
The polarity for the monitor diode must be set accordingly, see section Bias Voltage for the Monitor
Diode .
The ITC8000 modules come with separate inputs for laser forward voltage measurement. This
allows a 4-wire connecting scheme that eliminates measurement errors due to the voltage drop
caused by the injection current.
The temperature controller sensor input can handle different types of sensors. A missing sensor or
selection of a wrong type is detected by the ITC8000.
