QCL1200
The product has 1.2A Laser driving current and 5A tec driving current. It is suitable for many high power QCLs from various manufacture eg. Hamamatsu and AdTech Optics.
This module has an air cooling and a water cooling version. Air cooling version allow the QCL core cooled to room temperature in working state, while the water cooling version allow it down to 0 degree but requires external cold water cycler.
PRODUCT INFO
Our integrated laser driving module have most of the required functions to use tunable diode lasers, QCLs and other current driving lasers.
It has a digital controlled PID temperature loop that read the NTC and drive the TEC inside the laser package. The control loop has 0.1-degree accuracy and adjustable transient response. The case provides proper heat sink for the laser.
The module uses a high-speed current driver for laser driving. Driving signal can be chosen from constant current or sweep scan, with or without sinewave modulation.
Signal from detectors are to be feedback into the analog port. Our module will demodulate the signal with its base frequency and double frequency. (The use of double frequency demodulation is referred to Wavelength Modulation Spectroscopy theory). Results can be acquired through console(digital) or DAC port(analog). We even integrated a wavelet based peak detection algorithm. That means when properly set up, the module can directly output the absorption results!
All functions are accessed through our PC software or through terminal console.
