9.68um high power benchtop DFB-QCL mid-infrared quantum cascade laser 100mW (TDLAS integrated control module)

QCL9680DFB-9.68um high power benchtop DFB-QCL mid-infrared quantum cascade laser is a mid-infrared test laser developed by Idealphotonics. The low loss of the atmospheric window is conducive to the test research of space optical communications. Our benchtop light source has high power and does not require ITAR review, which is an excellent choice for commercial mid-infrared test light sources. The tunable range exceeds 100nm and the output power is greater than 100mw to meet the industrial needs of customer testing. Our laser has built-in Znse collimated output, stable output power, and high temperature and wavelength stability, which is several orders of magnitude higher than the stability of traditional high-power quantum cascade lasers.

Product features：High power、 Compact structure、 Intelligent software control、 Built-in FPGA

Application area：Mid-infrared test light source、 Mid-infrared device analysis

Laboratory testing

Using a 9.68μm laser (outputting collimated light), a 5-meter-long optical path miniaturized mid-infrared gas absorption cell, and a PCI-4TE-9-1x1 infrared detection module, we set up the NF₃ gas absorption measurement experiment.

NF₃ gas absorption measurement experiment system diagram

TDLAS dedicated control software interface

Steps:

1. Connect the 9.68μm quantum cascade laser to the power supply and USB, and turn on the laser through the dedicated TDLAS control software;

Connect the infrared detection module at one end of the gas absorption cell, and align the laser with the light inlet of the gas cell at the other end, and adjust the position of the laser to make the optical axis consistent;

The signal received by the detector is connected to the laser, and the second harmonic signal demodulated by the phase-locked amplifier is connected to the oscilloscope for observation;

Tuning the laser phase, current, gain and temperature to obtain the best signal waveform.

Test results and analysis verification:

The second harmonic of NF₃ gas absorption is tested as follows:

In order to verify that it is the absorption of NF₃ gas, we queried the database parameters as follows:

We can see that the absorption peak in the database corresponds exactly to the absorption peak measured on the oscilloscope, which also verifies that the absorption spectrum on our oscilloscope is the absorption of NF₃ gas.
