Product Overview:

Low Noise Laser Diode Controller for TDLAS/Gas Sensing

These fully integrated laser diode control and mounting modules are designed for precision control of single mode laser diode modules in research labs and for product integration. The low noise version is offered as a solution with noise performance that is perfectly suited to gas-sensing and TDLAS applications.

Precision Temperature Control for Maximum Wavelength Stability

The controller is equipped with a high-stability temperature controller to ensure the highest level of power and wavelength stability. The temperature controller delivers up to 14 W power to the TEC.

Comprehensive Laser Diode Protection

The integrated laser diode protection circuits protect your device at all times. The user-set current limit and user-set temperature limit clamp both the bias current and the operating temperature to prevent damage to the laser. Soft-start current ramp to the user defined current set-point protects the laser from the possibility of thermal shock or current surges.

Finally, the integration of the mounting socket directly with the current source eliminates the need for cables and connectors from the current path, which greatly reduces the likelihood of ESD damage to the laser from plugging and unplugging cables, and prevents external electronic noise affecting the diode drive current signal.

USB Interface and Versatile Controller Software

The controller is equipped with a USB interface, and delivered with easy-to-use GUI software. Several software conrol libraries are provided for custom control software development, including Labview, DLLs, Hexa, and Python.

Multiple Pin Configurations Available

The TDLAS laser diode controller is available in two preconfigured pin configurations: T1 for Type-1, and T2 for Type-2. The standard pin configuration is T1; if you require the T2 configuration, please contact us and order TDLAS-T2.
