The LDC-119 laser diode controller delivers precision current and temperature control at an affordable price. These units offer a 1500 mA low noise current source paired with a high stability 28 watt TEC controller. Both functions are integrated into an easy to operate benchtop instrument.
Laser Diode Protection Features
These units offer the highest level laser diode protection available to ensure that your device under test is protected at all times. Soft-start current, current and temperature limits, and a fast shut-down sequence keep your device protected at all times. Additionally, transient filters and AC line filters protect the laser against brown-out or black-out power conditions. The precision TEC controller offers a full P.I.D. control loop for fast and efficient thermal stabilization. A back-panel safety interlock connector ensures that the laser diode current is not switched on until the user has determined it is safe to do so.
TEC Controller Features:
The full PID loop provides millidegree temperature stability, and can quickly stabilize high heat loads to the temperature set-point to reduce the risk of damage to your laser. User adjustable upper and lower temperature limits can be programmed to protect the laser diode and the Peltier device. Additionally, TEC output current limits are user-configured to protect the Peltier device from over-drive damage.
Modulation, Internal Function Generator, and QCW Pulse Modes:
In addition to CW (continuous wave) mode of operation, the LDC-119 laser diode controller offers flexible modulation capabilities and a QCW mode. The rear panel of the controller has a BNC input for an analog or TTL digital modulation input with a 10k Ω input impedance. The controller has an internal function generator which can be used to set the quasi-CW pulses. In QCW mode, the user can also set the 100μs to CW pulses from a remote TTL signal source.
Front Panel and Remote User Interface:
Controller setup is fast and intuitive via the front panel LCD display and alphanumeric interface, with a simple to use menu structure and key pad. These systems come with standard an RS-232 interface. The included LabView driver GUI makes set-up and control of the system fast and simple. The controller can be ordered with a USB interface; contact us for more information.
