The CLD1010LP Laser Diode Driver and Temperature Controller is compatible with pigtailed TO Can laser diodes that have an A, D, E, or G pin code. Furthermore, a short circuit must be applied across the interlock terminals of the LD OUT connector (pins 1 and 5 - see Fig. So I looked at KLD101 pin map and connected pin 1 and pin 5. The download button below links to VISA VXI pnp™, MS Visual Studio™, MS Visual Studio.net™, LabVIEW™, and LabWindows/CVI™ drivers, firmware, utilities, and support documentation for Thorlabs' ITC4000 Series laser controllers, LDC4000 Series laser controllers, CLD1000 Series compact laser diode controllers, and TED4000 Series TEC controllers. Many of our mounts include a TEC that supports temperature regulation of the housed laser diode, indicated by the thermometer symbol on the links below. Is it solely a limitation of my external source or do these controllers ramp the current between intensity levels? See the table to the right for assistance in choosing a power supply. This is a response from Stefan at Thorlabs. USB connectivity provides easy, plug-and-play, PC-controlled operation. The software packages support LabVIEW 8.5 and higher. You will not need a power meter to get the system working. Combined controller and mount for pigtailed laser diodes in TO can packages with B, C, or H pin codes only. However using a KLD101 it is possible to modulate the laser diode output by connecting a modulating signal to the rear panel MOD IN connector. Please also note that the maximum TEC current is limited to 1 A. They also each feature an RF Bias-T that allows the laser to be modulated between 200 kHz and 1 GHz with an external RF source (dependent on the specifications of your laser diode). Low level DLL libraries are included for applications not expected to use the .NET framework. In constant power mode the digital loop introduces a quantization error that depends on the power setpoint and its position on the laser diode current curve. !%Thorlabs GmbH%! Increase the proportional gain until the circuit starts to oscillate. Under this example, the current is referred to as the Manipulated Variable (MV). If you increase this gain too much, you will observe significant overshoot of the SP value and instability in the circuit. The KLD101 also enables the maximum drive current current to be set to prevent damage to the laser diode by accidental overdriving. The effects may range from immediate and permanent damage—caused by the burning up of the diode—to a shortened diode life span. With regard to the modulation, the contribution of modulation current is added to the current set by the software or the output knob. Laser Diode Drivers The LD1100 and LD1101 Laser Diode Drivers are constant-power laser driver modules that support common laser anode and common laser cathode pin configurations. The C# example projects can be executed using the included .NET controls in the Kinesis software package (see the Kinesis Software tab for details).

If the laser diode was purchased from us, we are able to reterminate the fiber (assuming the break occurred 10cm or more away from the boot). In Constant Current Mode, the home screen emphasizes the laser diode current and temperature and displays their respective setpoints. Shop x. So frustrating!! Our laboratory bought your company’s TCLDM9, TTC001, TLD001 and two laser diodes. What setting should I choose? I expect the photodiode current to be between 50 and 500 uA. A response from Tyler at Thorlabs: We will contact you to help with the setup of your laser source. By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the APT and Kinesis controllers in a single application, while only having to learn a single set of software tools. The output of the PID control circuit, u(t), is given as, whereKp= Proportional GainKi = Integral GainKd = Derivative Gaine(t) = SP - PV(t). Operating current at 10 mW for this 405nm laser on the attached data sheet is 60 mA. While manual tuning can be very effective at setting a PID circuit for your specific system, it does require some amount of experience and understanding of PID circuits and response. The digital display on the top panel includes a backlight that can be dimmed or turned off using the top panel menu options. Each module has an output beam shape that is either elliptical or round, as indicated in the tables below. As a member of the K-Cube family of products, this driver can be controlled locally using the screen and switches on the unit, or it can be controlled using a PC via the USB interface and included software. Laser diode drive current can be changed to voltage by resistance connected to ILM, and the increase of this voltage is limited under current limit voltage (Typ.0.15V).

Ideally for my experiments I would like to pulse a laser diode very quickly (ie. Thank you. However, in some cases overshooting the SP value by any significant amount must be avoided and thus a higher derivative gain (along with lower proportional gain) can be used. Twist the three leads from the driver to the laser to minimize pick-up. The K-Cube controller achieves its best performance when used with a suitable temperature controller and a laser diode mount with an integrated TEC element. Second, why there is a note ‘laser driver settings not yet implemented’ when clicking the ‘settings’ button in the APT software? Each unit contains a front-located power switch that, when turned off, saves all user-adjustable settings, as well as two bidirectional SMA trigger ports that accept or output a 5 V TTL logic signal. Thorlabs Laser Diodes, Unbiased LASER DIODE SELECTION GUIDE, Compare all Manufacturers and Product Data Sheets on One Site, 370nm to 2350nm The letters making up the acronym PID correspond to Proportional (P), Integral (I), and Derivative (D), which represents the three control settings of a PID circuit.

Options range from individual laser diodes and DPSS lasers to complete laser solutions such as fiber-coupled lasers, HeNe lasers, femtosecond lasers, and nanosecond pulsed lasers. In additional to a full complement of safety features, such as a soft-start mode, current and temperature limits, and external interlock compatibility, the CLD1010LP and CLD1011LP controllers both include a switchable noise reduction filter and a modulation input. Too low and the circuit will be significantly slower in responding to changes in the system. When controlled locally via the touch screen, the resolution of the laser diode driver is limited by the display; the full resolution can be accessed when the device is controlled remotely. Hello, thank you for contacting Thorlabs. In constant current mode, when the laser is not enabled, you should be able to set the output current or turn the pot until you reached the desired value. Can I read the photodiode current while the unit is in constant power mode? Response from Radu at Thorlabs: Hello Young Ho Yun. Your proportional gain should then be set to roughly half this value. Optical Table Mounting PlateEach unit comes with a mounting plate that attaches to the base of the module. One or more of the controls can be utilized in any servo circuit depending on system demand and requirement (i.e., P, I, PI, PD, or PID). They support a maximum operating current of 200 mA, a maximum compliance voltage of 3 V, and modulation bandwidths up to 100 kHz (see the table to the right). Laser Diodes by Wavelength Laser diodes, which are capable of converting electrical current into light, are available from Thorlabs with center wavelengths in the 375 - 2000 nm range and output powers from 1.5 mW up to 3 W. We also offer Quantum Cascade Lasers (QCLs) with center wavelengths ranging from 4.05 to 11.00 µm. With the laser diode controllers of the LDC200C series, laser diodes can be driven in constant current (CC) or constant power (CP) mode. In Constant Power Mode, the home screen emphasizes the laser output power and diode temperature. See section 3.6 in the. Note that the KLS635 and KLS1550 are twice as long as a standard K-Cube and occupy two ports on the controller hub. This output is fed into a control device, its value is fed back into the circuit, and the process is allowed to actively stabilize the circuit’s output to reach and hold at the set point value. Thorlabs offers laser diode mounts for Ø3.8 mm, Ø5.6 mm, or Ø9 mm TO can packages. The tables below are designed to give a quick overview of the key specifications for our laser diode controllers and dual diode/temperature controllers. The hub vastly reduces the number of USB and power cables required when operating multiple modules. In that event, the circuit will further increase the amount of current through the TEC (integral control) by looking at the previous errors and adjusting the output in order to reach the desired value. These controllers can be operated in constant current or constant power mode; however, only laser diodes that include a monitor photodiode (pin codes A, B, C, and D) are compatible with constant power mode. Response from Mike at Thorlabs: You must ensure that when you set the photodiode range that the laser current is turned up to the current limit.
