TDLAS is a very modular laser diode driver which has been developed for gas sensing applications. It contains a lot of functionalities like internal and external modulation and many libraries for system integration.

TDLAS has a very low current noise level with low setpoint drift and noise close to measurement instrument ground level ;  It is an ideal driver for butterfly laser diodes such as NTT,  Eagleyard,  Nanoplus,  Eblana etc. TDLAS has a small form factor and is also available at board level. This makes it compatible with most of the OEM integration constraints. A multi channel version is also available  :  multi channel laser diode driver.

TDLAS Key features :

  • Very low current noise with low set-point drift and noise close to noise measurement instrument ground level.
  • Ideal for laser diodes such as NTT, EagleyardNanoplusEblana etc.
  • External current modulation with adjustable modulation transfer function (0 to 20 mA/V)
  • Sinus, triangular or square wave internal modulation
  • High resolution current level adjustments
  • 1 mK precision integrated TEC temperature controller
  • USB Interface with GUI & programming tools, software suite, DLL & labVIEW Libraries
  • Contains many functionalities for gas sensing techniques such as TDLAS, CAES, ICOS, CEAS, PS-CRDS, NICE-OHMS etc.
  • Safe start-up and operations, with safe shut-offs

The GUI software of this TDLAS laser diode driver lets the user have total control of all module functions. It includes several libraries for software integration ((LabVIEW VIs, DLLs, Hexa etc.)

TDLAS works alone or in series with other products in our range :

 

Complex systems, such as fiber lasers or gas sensing integrated systems, can be quickly developed on this module platform.

Butterfly Laser diodes such as NTT, EagleyardNanoplusEblana are perfectly well driven. Contact us for QCL laser diodes.
