Back and Top View of the KLD101 K-Cube LD Driver
The KLD101 K-Cube™ Laser Diode Controller is a compact, versatile module designed to drive a wide range of semiconductor laser diodes and LEDs. It supports operating currents up to 230 mA, a compliance voltage up to 10 V at 50 mA (>7 V at 230 mA), and both constant current and constant power operating modes. The KLD101 also enables the maximum drive current current to be set to prevent damage to the laser diode by accidental overdriving. 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.
The unit has a highly compact 121.0 mm x 60.0 mm footprint, allowing it to be positioned close to the rest of the system when manually adjusting the laser output using the top panel controls and convenient LCD display screen. A power switch on the front of the unit turns the K-Cube on and off, and the LCD screen displays information and settings upon startup, with or without a PC. When the unit is turned off, the K-Cube saves all user-adjusted settings for the next session. The power switch should always be in the "off" position when plugging in or unplugging the unit.
USB connectivity provides easy, plug-and-play, PC-controlled operation. The included Kinesis software package features .NET controls that can be used by third-party developers programming in C or C# and working in the latest LabVIEW™ or .NET compatible frameworks to create custom applications. For more details, please see the Kinesis Software and Kinesis Tutorials tabs. A USB 3.0 Type-A to type Micro-B cable is included with this K-Cube driver.

Laser Diode Out
The USB 3.0 port is compatible with a USB 2.0 Micro-B connector if the Micro-B connector is plugged into the shaded region in the photo above. A USB 3.0 Type-A to type Micro-B cable is included with the K-Cube.
I/O 1 & 2
These connectors provide a 5 V logic level input and output that can be configured independently to support triggering into and out of external devices.
Used to control the intensity of the laser output from an external source. This input can be driven from a 0 to 10 V voltage source. The input impedence is 16 kΩ.
2.5 mm Pin
The interlock jack must be shorted with the included 2.5 mm pin or an external user gate before the laser may be enabled.
Introducing Thorlabs' Kinesis® Laser Diode Controller
A major upgrade to the former-generation T-Cubes, the growing K-Cube line of high-end modules provides increased versatility not only through the new Kinesis software, but through an overhaul and update of their physical design and firmware.
Every K-Cube includes a digital display. In addition to basic input and output readouts, the K-Cube laser diode controller features a scroll wheel for adjusting the output current, power, and other settings. 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.

KLD101 K-Cube Kinesis Laser Diode Driver
Kinesis USB Controller Hubs
K-Cubes simply clip into place using the provided on-unit clips, while current- and previous-generation T-Cubes require the KAP101 Adapter Plate, shown in the animation below on the right. The hub vastly reduces the number of USB and power cables required when operating multiple modules. Note that the KLS635 and KLS1550 are twice as long as a standard K-Cube and occupy two ports on the controller hub.
K-Cube Table Mounting Plate
Unlike T-Cubes, every K-Cube includes a mounting plate that clips onto the base of the controller. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for more permanent placement on the tabletop.
Kinesis USB Controller Hubs
3- and 6-Port USB Controller Hubs allow multiple controllers to be connected to one PC for multi-axis applications. K-Cubes can be directly attached to the hubs while T-Cubes require a KAP101 Adapter Plate.
Thorlabs' Kinesis® software can be used to control devices in the Kinesis or APT™ family, which covers a wide range of devices ranging from small, low-powered, single-channel drivers (such as the K-Cubes and T-Cubes) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT Rack System).
The Kinesis Software features new .NET controls which can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW™ or any .NET compatible languages to create custom applications. Low level DLL libraries are included for applications not expected to use the .NET framework. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.
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. In this way, it is perfectly feasible to combine any of the controllers from the low-powered, single-axis to the high-powered, multi-axis systems and control all from a single, PC-based unified software interface.
The software packages allow two methods of usage: graphical user interface (GUI) utilities for direct interaction with and control of the controllers 'out of the box', and a set of programming interfaces that allow custom-integrated positioning and alignment solutions to be easily programmed in the development language of choice.

The Kinesis Software Package, which includes a GUI for control of Thorlabs' Kinesis and APT™ system controllers.
Kinesis GUI Screen for K-Cube Laser Diode Driver
Thorlabs' Kinesis® software features new .NET controls which can be used by third-party developers working in the latest C#, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications.
For a collection of example projects that can be compiled and run to demonstrate the different ways in which developers can build on the Kinesis motion control libraries, click on the links below. Please note that a separate integrated development environment (IDE) (e.g., Microsoft Visual Studio) will be required to execute the Quick Start examples. The C# example projects can be executed using the included .NET controls in the Kinesis software package (see the Kinesis Software tab for details).
Laser Diode Controller Selection Guide
The tables below are designed to give a quick overview of the key specifications for our laser diode controllers and dual diode/temperature controllers. For more details and specifications, or to order a specific item, click on the appropriate item number below.
The K-Cube Laser Diode Driver provides local and computerized control of a laser diode or LED. It features top-panel controls that support both constant current and constant power operation modes. The digital display on the top panel includes a backlight that can be dimmed or turned off using the top panel menu options. The front of the unit contains two bidirectional trigger ports that can be used to read a 5 V external logic signal or output a 5 V logic signal to control external equipment.
The unit is fully compatible with our Kinesis software package. Please see the Kinesis Software tab for more information.
Please note that this controller does not ship with a power supply. Compatible power supplies are listed below. See the table to the right for assistance in choosing a power supply.
The TPS002 supplies power for up to two K-Cubes* or T-Cubes. The cubes still require individual computer connection via USB cable.
The KCH301 and KCH601 USB Controller Hubs each consist of two parts: the hub, which can support up to three (KCH301) or six (KCH601) K-Cubes or T-Cubes, and a power supply that plugs into a standard wall outlet. The hub draws a maximum current of 10 A; please verify that the cubes being used do not require a total current of more than 10 A. In addition, the hub provides USB connectivity to any docked K-Cube or T-Cube through a single USB connection.
For more information on the USB Controller Hubs, see the full web presentation.
*The TPS002 can only support one KNA-VIS or KNA-IR controller or one KLD101 driver and should not be used to power any additional units as that may exceed current limitations.
