Thorlabs CLD1015 Compact Laser Diode Driver and TEC Controller
Description
Overview
The Thorlabs CLD1015 is a compact benchtop instrument that combines a precision laser diode current driver, a thermoelectric cooler (TEC) controller, and a laser diode mount into a single touchscreen-controlled unit. Designed for fiber-coupled lasers, superluminescent diodes and laser amplifiers in type 1 and type 2 butterfly packages, the Thorlabs CLD1015 gives researchers and engineers everything needed to drive and thermally stabilize a laser diode from one compact chassis, without stacking separate current and temperature controllers. Seven Star LLC supplies the Thorlabs CLD1015 across Oman and the GCC as part of its genuine Thorlabs catalog, giving regional photonics laboratories, universities, and telecom test facilities a dependable local source for authentic Thorlabs laser diode control instrumentation with responsive technical support.
Photonics engineers and laser system integrators choose the Thorlabs CLD1015 whenever a project needs a self-contained, low-noise laser diode driver and TEC controller with a full graphical touchscreen interface, rather than assembling a rack of separate current source, temperature controller, and mount hardware. Backed by manufacturer datasheet documentation, Seven Star LLC proudly supplies the Thorlabs CLD1015 across Oman and the wider GCC, with manufacturer documentation and technical support, supplied on request with lead time confirmed at quotation.
Measurement and Working Principle
The Thorlabs CLD1015 supplies laser diode current across a 0 to 1.5 A control range with greater than 4 V compliance voltage, delivering low-noise output of approximately 10 microamps typical without filtering and as low as 5 microamps with the internal filter engaged. Current is set with 50 microamp resolution over remote control and held to an accuracy within 0.1% plus 500 microamps of the programmed setpoint. In parallel, the Thorlabs CLD1015’s bidirectional TEC output supplies -3.0 A to 3.0 A with greater than 4.7 V compliance and more than 14.1 W of thermoelectric cooling or heating power, reading the laser diode’s NTC thermistor across a 300 ohm to 150 kilo-ohm range for temperature sensing from -55 degrees C to +150 degrees C with 0.01 degree C resolution. Closed-loop temperature stability on the Thorlabs CLD1015 reaches approximately 0.005 degrees C over 24 hours, keeping the laser diode’s emission wavelength and output power stable during extended measurement or test sequences.
Engineering Design of the Thorlabs CLD1015
The Thorlabs CLD1015 is built around a 4.3 inch color LCD TFT touchscreen at 480 x 272 pixel resolution, giving direct front-panel access to laser current setup, laser protection limits, photodiode monitoring input, TEC driver setup, PID control loop tuning, thermistor calibration, and system settings without needing a separate PC. The unit accepts standard 14-pin butterfly-package laser diodes in both Type 1 (pump) and Type 2 (telecom) pinout configurations, with the mount integrated directly into the chassis for simple, repeatable laser installation. A USB 2.0 interface supporting the USBTMC protocol and SCPI command set lets the Thorlabs CLD1015 be integrated into automated test benches and LabVIEW or Python-based measurement systems, while the compact desktop enclosure is powered by the included external desktop power supply, which delivers 12 V DC ±5% at 3.5 A.

Industrial Applications
The Thorlabs CLD1015 is widely used in photonics research laboratories and university optics departments across Oman and the GCC for driving and characterizing butterfly-packaged laser diodes during device evaluation and spectroscopy setup. In fiber-optic communications testing, the Thorlabs CLD1015 provides stable, low-noise current and precise thermal control for telecom-wavelength laser sources during transmitter qualification and component testing, where wavelength drift directly affects test repeatability. Laser diode manufacturers and packaging houses also rely on the Thorlabs CLD1015 during incoming inspection and burn-in testing of butterfly-package laser diodes, using its integrated mount to avoid separate fixturing for each device under test.
Because the Thorlabs CLD1015 combines current driving, thermal control, and mounting in one instrument, research groups across the region reduce bench clutter and cabling complexity compared with a traditional three-box setup of separate laser driver, TEC controller, and mount, while the touchscreen interface speeds up day-to-day parameter changes between different laser diodes. Working closely with plant engineers in the region, Seven Star LLC supplies the Thorlabs CLD1015 to laboratories, industrial facilities, and research institutions throughout Oman, Muscat, and the Sohar and Salalah economic zones, with lead time confirmed at quotation.
Educational and training laboratories in Omani and GCC universities also deploy the Thorlabs CLD1015 in photonics and laser-electronics coursework, giving students a single, intuitive instrument for learning laser diode drive and thermal-stabilization principles without the complexity of programming separate current and temperature controllers.
System integrators building laser-based sensing, spectroscopy, or optical communication test systems across the region use the Thorlabs CLD1015 as the core laser drive electronics, valuing its combination of touchscreen manual control and SCPI-based remote programmability for both prototype development and production test station deployment.
Seven Star LLC’s Thorlabs catalog, including the CLD1015, gives regional photonics buyers a single trusted local partner for laser diode drivers, TEC controllers, optical power meters, and related laboratory instrumentation, simplifying procurement for multi-vendor lab setups that previously required importing individual items from overseas suppliers.

Ordering Thorlabs items: what we need
Thorlabs item numbers are exact, so PM100D, PM400 and PM100USB are different products, and a console is normally ordered with a separately numbered sensor. Send the item numbers and quantities. For a power meter, add the wavelength, the power or energy range and the beam size, so the sensor can be checked. For laser diode drivers, give the diode pin configuration, the operating current and the TEC current. For motion controllers, name the actuator or stage to be driven. Mention the mains voltage and plug type you need.
