Both monitor inputs can be calibrated by a sensor response parameter to directly display the optical power in milliwatts. The switchable filter used for noise reduction is not embedded for devices manufactured before 2013. Both views shown below are looking into the connector. QPhotonics SuperDIL laser diode controller; Thorlabs model ITC 510; ILX Lightwave model LDC-3724B or similar; Newport model 6505 or similar; Device operating characteristics are function of temperature and the performance deteriorates rapidly at higher temperatures. The laser diode / LED drivers offered on this page are ideal for applications that require the controller to be integrated into a larger system. After the proportional gain is set, increase the integral gain until any offset is corrected for on a time scale appropriate for your system. Under this example, the current is referred to as the Manipulated Variable (MV). Dear Thorlabs, We have ITC4020 in our lab. The thermopile voltage reading will be lower (10% off) if the LD operates in QCW mode with the pulse width of 100us. Thorlabs - LDC4020 Benchtop Laser Diode Controller, 20 A / 11 V Products Home / Drivers & Mounts / Current Controllers / LDC4000 Series Benchtop Controllers / LDC4020 LDC4020 - Benchtop Laser Diode Controller, … The LDC4020 is shipped with the CAB4006 cable and CON4005 connector kit. The character size is enlarged as much as possible for easier reading. Best regards,
For manual optimization, the temperature PID control loop settings can be entered here. The function of Support for LD output noise reduction filter added is in v1.5.0, but when I update to v1.8.0. For each, a monitor input is provided. Here the measurement screen is configured to 2 values.

We also offer a variety of OEM and rack-mounted laser diode current & temperature controllers (OEM Modules, PRO8 Current Control Rack Modules, and PRO8 Current and Temperature Control Rack Modules). Use the legend below to quickly select the driver with the features that you need.
This is a response from Sebastian at Thorlabs. Thank you very much for your inquiry. 3. Is it possible to introduce in a new firmware the "save confirmation" feature?! Thorlabs also offers several dual laser diode current/temperature controllers and kits. You can control all parameters accessible on the front panel of the device also per USB. I ask about the capability and the method to connect (DAQ-500MHz bandwidth) with (ITC4001)to control the laser diode current to change the spectral frequency. You can freely select two, four, or six values to be displayed with optimized character size. The LDC4020 shorts the pin A1 A2 and A3 when the laser diode current is not switched on. I know that old modules allowed to do this kind of experiemnts, but I'm not sure how to do with this new one. – How much is the response time or frequency to control the laser current. For more details and specifications, or to order a specific item, click on the appropriate item number below. To tune your PID controller manually, first the integral and derivative gains are set to zero. We also provide loose 17W2 connectors for customers who wish to make their own cables. This function isn't display in LD Output Configuration. I will contact you directly to discuss the details of your setup in order to see if the sweep time you need could be achieved with the ITC4001. The ITC4001 has a USB connection which can be used to remotely program any desired temperature sweep. The software packages support LabVIEW 8.5 and higher. Via front panel the resolution is limited by the display. Thank you for the inquiry. Thank you very much. If the connection between current source and laser diode is interrupted, or the laser voltage exceeds the adjustable voltage protection threshold, the laser current is switched off. As you have left no contact data, please feel free to contact us at europe@thorlabs.com for further questions. Current Controllers Our laser diode current controllers include an easy-to-use K-Cube™ current controller, benchtop controllers, and PRO8 series rack models. To ensure accurate measurements, we recommend recalibrating the devices every second year. In general the gains of P, I, and D will need to be adjusted by the user in order to best servo the system. Combined controller and mount for laser diodes in butterfly packages only. LDC1300B - Laser Diode Controller for Butterfly Packages : Zoom. Compatible with Thorlabs' Laser Diode and TEC Controllers TO-packaged laser diodes are available in standard Ø3.8 mm, Ø5.6 mm, or Ø9 mm TO cans, as well as Ø9.5 mm and TO-46 cans. Many of our mounts include a TEC that supports temperature regulation of the housed laser diode, indicated by the … In doing so, it is able to partially compensate for the overshoot as well as damp out any oscillations caused by integral and proportional control. I'm interested in performing wavelength sweeps thorugh temperature changes. Shop x. A power limit can be set to restrict the control loop to a maximum laser output power.
