16 Amp Laser Diode Controller with 128 Watt TEC Temperature Controller Features
These high power current source and TEC controller instruments were designed to precisely control high power single emitter pump laser diodes from companies such as Lumentum, Lumics, Coherent and II-VI laser enterprise. These units offer a precision 16 amp current source to bias your laser diode as well as a full PID temperature controller. The current source offers industry leading protection for your multimode pump laser diode. The LDC-156 is an affordable, high performance solution for safely powering your laser and running at a stable temperature in laboratory environments.
Internal Function Generator & QCW Pulse Modes
In addition to CW (continuous wave) mode of operation, the LDC-156 offers flexible modulation capabilities and a quasi-CW mode. The rear panel of the controller has a BNC input for an analog or TTL digital modulation input with a 10K input impedance. The controller has an internal function generator which can be used to set the modulation signal or the quasi-CW pulses with a time base accuracy of 1.0%. In QCW mode, the user can also set the 20μs to CW pulses from a remote TTL signal source.
Temperature Controller Features
The integrated TEC controller drives TEC-based cooling loads with up to 128 Watt output: ± 8.00 Amps and ± 16.00 Volts. The full PID control 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.
The TEC sensor input is suitable for use with 10k Ohm NTC thermistors. There is an auxiliary control capable of 24 V and 800 mA output that can be used to drive an external cooling fan.
User Interface and Cable Connectors
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.
The controller includes two connectors on the back panel: There is a 15-pin D-Sub connector, wired for the TEC control and ancillary functions. The second connector is a high-current two-pin connector, type DSUB-2W2, specifically for connection to the high-power laser diode module.
