CW LWIR QCL from 10µm to 17µm - HHL Packaged

These lasers are DFB Quantum Cascade  lasers (QCL) that emit Continuous Wave  (CW) infrared light at room temperature  with wavelengths ranging from 10  microns to 17 microns. The lasers are  mounted on a thermoelectric cooler  inside a sealed High Heat Load (HHL)  package integrating a collimation lens  and a thermistor to readout the laser  chip temperature.


Amazing pulsed-operation features

Pulsed operation is an attractive option for SIMTRUM. It means less electrical power  consumption of the package, higher  temperature operation, larger tunability, access  to even longer wavelengths, smaller heatsink  and easier integration in systems. A unique  feature of the long wavelength SIMTRUM product  is its very small spectral chirp during the pulse,  typically <0.04 cm-1/100ns. It allows intrapulse  spectroscopy without the need of high-speed  detection or QCW spectroscopy without a  degradation of the spectral resolution (down  to 0.01 cm-1) to be implemented. (SIMTRUM can provide a dedicated electronics for pulsed  operation.)



By controlling the chip’s operating  temperature through the Peltier element inside the laser’s package, customers tune the emission wavelength without mode hopping while keeping a longitudinal single-mode operation.


For larger tuning range, pulsed operation is an attractive option  because at these long wavelengths, the intrapulse linewidth broadening is relatively smaller than at shorter  wavelengths.





             The red curve indicates the maximum chip temperature as a function of the wavelength for CW lasers and the green curve indicates the maximum chip temperature as a function of the wavelength for the pulsed laser.



SIMTRUM can provided any wavelength in the 10-17 µm range and below are examples of gases that can be measured by spectroscopy at specific wavelengths.
